Contacting Info-ZIP Do you have any mailing lists for discussions. All file times will appear to shift by an hour. Finally, run UnZip just as on any other system (see FAQ #2). (There may still be errors in the archive, but if so, they weren’t particularly relevant to UnZip’s processing and are presumably quite minor. The standard version 5. How do I make a DOS (or other non-native) self-extracting archive under Unix. , EBCDIC) and encodings of international characters (e. 3
and earlier all HexView reported a buffer-overrun vulnerability (CVE-2004-1010) in Zip 2. 2 and later have a work-around for the problem, however. Once the noise level exceeded the convenience factor, it had to go. 50, and a patch (slight overkill, but apparently effective) is available on the Bugtraq page that reported the problem. (Thanks to Jan Echternach and John D. This results in an off-by-one-hour problem in some extracted files, especially around April and October when locales that observe DST typically switch between it and Standard Time. ) How do I make the Win32 version (32-bit Windows) of Zip 2. The root cause is a longstanding bug in Windows NT, Windows 95/98, and Windows CE. , 1024-character maximum path length, a list of invalid filename characters, etc. 51
and earlier all c0ntex reported a buffer-overrun vulnerability (CVE-2005-4667) in UnZip 5. 3, and while there may have been some lingering oversights in that series, the UnZip 5. Do not type “run” before the command. ) UnZip 5. 42 have a directory-traversal security vulnerability that allows them to unpack files in unexpected places. 3 related to deep directory paths, which could potentially lead to local privilege escalation (e. Can I use the Zip or UnZip source code or executables in my commercial product. 4; check UnZip with “unzip -v”). (The only reported oddity was in listing the archive’s contents; UnZip has no way to know that the true file size is bigger than what the zipfile directory reports. 0 at the heart of Windows 9x, does not support VFAT or FAT32 long filenames. You need to upgrade your copy of Internet Explorer to version 4. Internally it uses DOS-format dates by default (no problems until 2108; i. Because’s fseek’s offset argument is usually a signed long integer, on 32-bit systems UnZip will not find any file that is more than 2 GB from the beginning of the archive. , all knowledge of the file to which the link pointed was lost within the archive. 2 and seems to have been the only problem. 6 UnZip was unable to allocate memory during decompression to disk. To check what compiler was used to create any of our pre-compiled executables, do “unzip -v” or “zip -v” with no other arguments. So the last file in the archive can potentially be arbitrarily large (in theory, anyway–we haven’t tested this), but the combined total of all the rest must be less than 2 GB or 4 GB, respectively. , in the case of automated, UnZip-based unpacking of user-specified archive names by a privileged account–not a terribly likely scenario). Txt) will look something like this: @ invalidsubdiroldname. This table was created in August 2001 and last updated in May 2005. Those who wish to download older binaries or compile their own versions may still do so, or you can wait for UnZip 6. DOS and its derivatives (Windows, OS/2, etc. Exe // doesn’t recurse as expected For now, the previous method (using -r and -i) will work. ) The workaround is to disable 64-bit deflate support when compiling 16-bit UnZip ports (define NO_DEFLATE64). This is fixed in version 5. 50 16-bit ports
(e. Exe // recursively archive all *. That said, as of mid-2006, Zip 3. 3 and earlier, possibly also 5. ), as described above; we’ll assume DOS in the following example. Exe files This bug was fixed in Zip 2. 13 The zipfile was missing or empty (typically when updating or freshening). The documented way in 2. 50
and earlier virtually all All versions of UnZip through 5. UnZip displays only two digits of the year when listing files (in most formats), so if you take that output and sort on the year field, it will fail. First, redirect ZipNote’s output to a file that you can subsequently edit: zipnote invalid-dirseps. All older releases are still covered by our old COPYING file (UnZip) or the README file in official Zip distributions. 2 recurse through subdirectories and archive only files matching a certain pattern. 0 or later. X], and possibly other file utilities [ls, rm, etc. 16 The command-line parameters were specified incorrectly. Then extract the UnZipSFX stub from the distribution and prepend as if it were a native Unix stub: unzip unz552x3. 4 or later], the file system [at least Reiser and ext2 are supported], the C library [glibc 2. Finally, note that this is not a warranty or certification of Y2K readiness. Yes, at least the UnZip 5. 82 No files were found due to bad decryption password(s). This is a known bug with HPFS386-based network drives (LAN Server 4. , HPFS-Access, Amos, etc. Summer Time) and is being extracted during Standard Time–or vice versa–Windows applies the current timezone offset (including DST) to the extracted file instead of using the offset that was applicable on the date the file was created or otherwise modified. There have been a few over the years. Last updated 4 October 2008. X zipfile specification (but see the PKZIP 4. ) 6 ZipSplit was unable to create an archive of the specified size because the compressed size of a single included file is larger than the requested size. Why do files with extended attributes get extracted under OS/2 with the current time while all other files retain their original timestamps as expected. 12 or earlier); you’re extracting to an HPFS386-based drive. These are fixed in version 5. Longer answer: older versions of WinZip (and, no doubt, some other clone zippers) stored filenames using backslashes as directory separators in violation of PKWARE’s appnote, which specifies that forward slashes (‘/’) should be used. All of these things suggest that it’s time for a brand-new format, not just a few more patches on an aging standard. How can I recover my data. Although it appeared that standalone unshrinking was not covered, the owner claimed otherwise in public statements, and the matter was never tested in court. Txt (which is included with all official distributions), and are defined as follows (on all platforms but VMS): UnZip value meaning 0 Normal; no errors or warnings detected. , the latter cannot be decoded on other systems). 2, but that version in turn has a bug in its new -R option: zip -R foo. 4 DLLs and Zip 2. However, if and when the Windows bug is ever fixed, it’s possible that Info-ZIP’s workaround will recreate the bug in reverse. It is probably not 100% complete (particularly with respect to very old bugs), but it’s close: program platform nature of bug Zip 2. 11 No matching files were found. UnZip’s error codes are documented in its man(ual) page, unzip. C with optimization turned off (no -O or +O2 option) or turned down to the lowest level (+O1). 5 UnZip was unable to allocate memory or unable to obtain a tty (terminal) to read the decryption password(s). X could result in silent corruption. , any version of zlib before 1. 0 or Warp Server), and IBM has not provided a patch. However, we do have a report that a user of the Win32 versions of Zip and UnZip succeeded in compressing and extracting a 7 GB database file. , bogus internal offsets) that makes it appear to be truncated. Note that paths specified as arguments must be in zipfile format–that is, forward slashes (“/”), no drive letters, etc. All of the quotes in the ZipInfo line are necessary, too, so don’t delete any of them, either. Either way, the comp. In effect, this is yet another (fourth. Txt // create renaming template ZipNote’s output (in invalid-dirseps. ) directory-traversal variant. The currently available 32-bit executable in unz552x3. 18 Zip could not open a specified file for reading; either it doesn’t exist or the user running Zip doesn’t have permission to read it. 50 have a pair of directory-traversal vulnerabilities, both somewhat subtler than the original one (see above). The procedure is basically described in the UnZipSFX man page. 3 all When compiled with either BIG_MEM or MMAP defined (MMAP overrides BIG_MEM if both are defined), Zip will silently corrupt stored (uncompressed) files when forced via either the -0 (“store”) or -n (“don’t compress these suffixes”) options. ) Zip’s error codes (and those of ZipSplit, ZipNote, and ZipCloak) are documented only in the ziperr. Info-ZIP’s utilities use the normal C library functions to read and write files; those functions, in turn, depend on the operating system to provide file-system support. That’s wrong. We have not tested it ourselves, but it sounds like it does exactly what’s needed. Exe // extract the DOS SFX stub cat unzipsfx. Exe was compiled with djgpp 2. 42
and earlier virtually all All versions of UnZip through 5. 80 The user aborted UnZip prematurely with control-C (or similar) 81 Testing or extraction of one or more files failed due to unsupported compression methods or unsupported decryption. 0, which will once again enable unshrinking by default. The second involves the use of a quoted “/” character, which could be used either to convert a harmless “. We believe this bug affects all previous versions of Zip, as well, and most or all supported platforms. 41 and later will extract them again. ) Zip-Bugs, the internal mailing list for the core development team, was shut down in August 2003 in favor of a web-based contact form. This problem does not appear to affect any of Info-ZIP’s command-line tools or MacZip. Two reasons: you’re using an old version of UnZip (5. Total size of archive 256 TB While the only theoretical limit on the size of an archive is given by (65,536 files x 4 GB each), realistically UnZip’s random-access operation and (partial) dependence on the stored compressed-size values limits the total size to something in the neighborhood of 2 to 4 GB. To our knowledge, this has not yet happened. There is no capability in Unix UnZip to treat backslashes as directory separators (since they’re perfectly acceptable filename characters, just like colons, quotes, and pretty much everything other than forward slashes), so if you want to extract the archive as a subdirectory tree without hacking the source code, you’ll need to rename the archive entries. 31) would print “100” instead of “00” for the year 2000; this is fixed in 5. (Thanks to Mark Adler for verifying this. “-ipa” is reported to generate incorrect code sometimes, however. So while Info-ZIP’s Win32 versions do support long filenames in Win9x DOS boxes, they don’t even run under plain DOS. This restriction may be relaxed in a future release. ), it will support long filenames under Windows 95/98/ME (not NT/2000) or short filenames under plain DOS. )   UnZip 5. 15 Zip could not open an output file (typically the archive) for writing. Uncompressed size of a single file 4 GB This is also not a hard limit, in that the deflate algorithm used in all recent releases has its own “end of stream” marker. The -R bug is fixed in 2. Yup, there are recursion bugs in the Win32 port of both Zip 2. ) Why does my Unix UnZip extract flat filenames with backslashes in them instead of a subdirectory tree. Specifically, if an archive contains files with leading “/” characters (i. 9 Zip was interrupted by user (or superuser) action. This is fixed in version 5. ) Also note that in August 2001, PKWARE released PKZIP 4. (Note that the same bug will affect any program that uses the DosSetPathInfo() call. 00 for platforms that have the fchmod() system call. Thus any of the following workarounds will suffice: never use the -0 or -n options always use the -9 (“maximal compression”) option, which overrides -0 and -n use the default compilation options, in which neither BIG_MEM nor MMAP is defined Note that there are some systems that appear to be immune to the bug, including DEC/Compaq systems with the DEC/Compaq C compiler (but not with the GNU C compiler). Note that this bug affects both decryption of zipfiles created elsewhere and encryption of zipfiles created on HP-UX (i. See also Secunia’s advisory. , DOS) For all ports using 16-bit integers, textmode output (-a or -aa options) is broken in such a way that half of the output-buffer chunks are silently skipped. 1 is this: zip -r foo. ) Note that Zip will first store in memory the path/filename and various parameters for every file that will be in the final archive; the actual limit on the number of files may be determined by the amount of RAM and/or virtual memory available on the system. 0 (success) is translated to 1 (VMS success), and all others are multiplied by 16 and added to 0x7fff0000 plus a final offset of 0, 2 or 4 depending on whether the return code is a warning, a “normal” error, or a severe (fatal) error, respectively. 50 with support for large files and archives via a pair of new header types, “PKx06x06” and “PKx06x07″. , not extracting), J. We don’t yet know when Zip and UnZip will support this extension to the format. (Thanks to jelmer and ITO Tsuyoshi for reporting them. ) UnZip 5. 12 There was nothing for Zip to do (e. ) zipnote -w copy-of-invalid-dirseps. You also have the option of displaying dates in yyyymmdd. ) This is fixed in version 5. Exe” $ zipinfo == “$disk:[dir]unzip. Where “disk” and “dir” refer to the true disk and directory where unzip. , UTF-8), unnecessary redundancy, and merely acceptable (but no longer outstanding) compression efficiency. Miscellaneous When are the next versions of Zip and UnZip coming out. ” This will be fixed in version 6. 1 @ (comment above this line) @ invalidsubdiroldname. There is a bug in older versions. Thanks to Joe Forster, Bruno Binet and Jim O’Dell for the tip. 3 A severe error in the zipfile format was detected. Are Info-ZIP tools affected by the zlib double-free security vulnerability. I forgot the password on my archive. 1’s -y option, symbolic links got stored as empty files–i. If the password was very short (i. (You may wish to do this to a copy of the archive, just in case something goes wrong. ) We addressed this problem in 1997 for UnZip 5. 20 that breaks Zip’s encryption code and UnZip’s decryption code. But since you asked: It depends a bit on how you use Zip and UnZip, but by and large there shouldn’t be any problems. (Thanks to Ulf Harnhammar and AusCERT’s Matthew Aburn for the pointers. X OS/2 3. (The operating system also must have support for large files; for Linux, this involves the kernel [2. 2 A generic error in the zipfile format was detected. 1 any Unix With Zip 2. ) UnZip 5.   WiZ 5. 3 @ (comment above this line) @ (zip file comment below this line) Note that this particular example changes all backslashes to forward slashes, shortens two filenames (oldname. 4x series should be completely fixed. X compiler (now part of Cygwin. 50

Common Problems Why does UnZip say “‘shrink’ method not supported”. Your best bet, therefore, is to try Chris Jones’ LFNDOS VFAT/FAT32 device driver for DOS, which is somewhat similar to the OS/2 HPFS device drivers already available for DOS (e. Note, however, that ZipNote does make a temporary copy of the zipfile while working (in case it’s interrupted), so you will briefly need room for the extra temporary copy in addition to any copy you may have made. 10 Invalid options were specified on the command line. First grab the appropriate UnZip binary distribution for your target platform (DOS, Windows, OS/2, etc. ) 1 One or more warning errors were encountered, but processing completed successfully anyway. Our original mailing lists died several years ago, thanks both to the ever-shifting sands of mail servers and to spammers. ) How do I report bugs. (If even one file is successfully processed, however, the exit status is 1. Older versions (5. (It may also affect other tools, including some shells and gdb itself. Archive Limits and Known Vulnerabilities What limits (number of files, size of files, etc. (The older forum at QuickTopic is also available in read-only mode; click the “printer-friendly” link to see the archived, non-spam messages in compact form. 3 DLLs (and later versions). Web page maintained by Greg Roelofs. ” This can be ignored. Some CD-ROM file systems have an 8-level subdirectory limit. Deutscher for reporting this bug and Christian Spieler for identifying it in the source code. ) 7 The format of a zipfile comment was invalid. ” components (“previous directory level”), UnZip will unpack the files in the indicated locations, possibly creating directory trees in the process–and, if the -o (“overwrite”) option is given, quietly destroying existing files outside the intended directory tree. Your web page says (used to say) Jet Propeller Laboratory. 1 @ (comment above this line) @ invalidsubdiroldname. If it was more than 8 or 10 characters and not restricted to a small subset of ASCII (e. The first one (CVE-2003-0282) involves placing one or more invalid characters between a pair of dots; the bogus characters are filtered out, leaving a “. This is fixed in version 5. It affected many archivers and other programs, and it could be fixed only by patching the NFS server. (This should never happen; it indicates a programming error of some sort. (For what it’s worth, the same algorithm was and is used in other utilities that have been included in every Linux and FreeBSD distribution that has ever shipped or been downloaded, and no one has ever complained about that. Plain DOS, even the DOS 7. We believe the statements above to be completely truthful and accurate, but we accept no liability for errors in either the statements or the software. Newer versions of WinZip correct that bug, so if you created the archive in question, you should upgrade. Because the stored CRC-32 value is consistent with the corrupted data, testing with UnZip will not expose the error; only extraction and byte-for-byte comparison with the original files will. On the other hand, Info-ZIP had no particular desire to become the test case. 51
and earlier Unix only Albert Puigsech Galicia noted that one of UnZip’s backup-related features, the restoration of file permissions including UID and GID bits, could constitute a privilege-escalation vulnerability (CVE-2005-0602) insofar as (1) UnZip doesn’t emit a warning when restoring such bits, and (2) it’s the default behavior in version 5. This is fixed in version 5. 11 Reading or seeking (jumping) within an input file failed. And the DOS versions mostly don’t support long filenames, with one exception: if UnZip is compiled with the free djgpp 2. (On 64-bit IRIX with the native compiler, the options “-mips4 -64” or “-mips4 -64 -ipa” [for both compiling and linking] may help. ” sequence into a harmful one or to create absolute (leading-“/”) paths. This is fixed in version 2. 50 have a filename-mismatch vulnerability whereby files can be extracted with paths and names other than those that appear in archive listings. (Thanks to Jan Echternach for reporting this. So far these headers are undocumented, but most of their fields are fairly obvious. Yes, this is a fifth directory-traversal variant. (What happened to the Zip-Bugs address. , relative to the top-level/root directory) or with “. Exe // create the SFX archive zip -A yourDOSzip. This was a known bug in Solaris (Sunsolve ID 4071076), AIX (IBM APAR IY06322) and possibly other Unixen that seems to have been exacerbated by Red Hat’s knfsd. 3) and one subdirectory name (othersubdir), and lengthens one filename (oldname. We don’t recall the exact details, but an OS/2 fixpak is/was available to take care of the problem. 0 of Norton AV (for Windows 95/98) does not report any such thing. , essentially useless), there are various brute-force password-crackers available. The double-free bug affected only the version of inflate() in zlib; UnZip’s version is not vulnerable, and Zip does not use inflate(). 0 are coming along and should be released sometime in the first half of 2007. See the next item for more information about that. Compression FAQ list is the place to start looking. Many thanks to Michael Kilby for tracking this down. This is almost certainly an error in the Symantec “emergency boot disk,” which, according to a Symantec response on their German web site, has an outdated virus signature file. There is an optimization bug in the native (non-GNU) HP C compiler for HP-UX 10. ) generally limit paths to 256 characters or less; Unix systems typically have a 1024-character limit. See our new(er) open-source, BSD-style license for details. Windows Chad Loder of Rapid7 discovered a crash bug and potential security vulnerability in WiZ, involving very long filenames inside archives. It’s a bit late to be worrying about that now. Yes, Sherlock, we know. ) Can I expect any Y2K problems. 8 Testing (-T option) failed due to errors in the archive, insufficient memory to spawn UnZip, or inability to find UnZip. , in the case of automated, Zip-based backups by a privileged account). Please direct all Info-ZIP queries (availability, ports, bugs, corrections, etc. Note that there are other limitations of the zipfile format beyond its dependence on 16-bit and 32-bit fields. 1 and 2. Ordinarily the local and central filenames match, but an attacker could modify the names (and paths) in the local headers in order to cause files to be created in unexpected locations. See UnZip’s COPYING and INSTALL files for more information. The UnZip DLL is believed to be thread-safe. When you’re done editing the output file, use ZipNote once more to apply it to the zipfile. (Note that Zip and ZipSplit still do not support the creation of PKWARE-style multi-part archives. 5 Internal logic error. See Rapid7’s advisory for test archives and subsequent links, including CERT and CVE. In the short term, it is possible to improve Zip and UnZip’s capabilities slightly on certain Linux systems (and probably other Unix-like systems) by recompiling with the -DLARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64 options. Exe // fix up internal offsets That’s it. Can I use the Windows DLLs with Visual BASIC. We may set up new lists on SourceForge at some point, but in the interim, a web-based forum, with both bug-reporting and discussion areas, has been set up. 52: the new -K option must be given explicitly in order to restore UID, GID and sticky bits. 2 @ (comment above this line) @ invalidothersubdiroldname. As convenient as the real e-mail address was to everyone involved, it turned out to be equally convenient to the masses of header-forging viruses and spam messages propagating across the Internet. 2 will emit a warning about a “preamble of xxx bytes. (And no, we’re not volunteering, either–although we have discussed what we consider some of the requirements for such a new format. Exe // doesn’t recurse as expected under Windows 9x, NT This is what actually works: zip -r foo. We apologize for the inconvenience. (Earlier releases will not. Add some lines similar to the following to your LOGIN. Hhmmss format (unzip -ZT) for sorting, if you wish. (Aside: You can see the bug in action, completely independent of Zip and UnZip, by saving a Windows directory listing just before the switch and comparing it with one taken just after the switch. (Thanks to Stefan A. This is fixed in version 2. Note that it’s possible that some PC-based C compilers or libraries have Y2K bugs in them that would affect Zip and UnZip. VMS file included with our VMS distributions. ) One workaround is to “ensure that any directory which is being used by unzip to decompress files is writeable only by the user”; another is to “set the sticky bit on the directory’s permissions. The Zip DLL is not. ] if redirection is involved. And on 64-bit systems, UnZip won’t find any file that’s more than 4 GB from the beginning (since the zipfile format can only store offsets that big). Also note that 16-bit DOS versions of Zip are limited to around 16,000 files. ) UnZip 5. No–unless UnZip is compiled with USE_ZLIB defined and the relevant version of zlib has the bug (i. Txt // rename zipfile filenames That’s it–no recompression required. Copyright © 1995-2008 Greg Roelofs. UnZip (and Zip, and all of the other Info-ZIP utilities) must be set up as a VMS foreign command, as noted in the README. There are no particular limits on zipfile filenames when renaming with ZipNote (other than the 65,535-character limit on filename lengths), but note that the target filesystem may have much more stringent limits (e. 7 UnZip was unable to allocate memory during in-memory decompression. (This was not a Zip bug, per se. Why does WiZ say “Failure creating property sheet” when I pick the Options menu item. Other possibilities include Duncan Murdoch’s DOSLFNBK and LFNSORT utilities. This is fixed in version 5. This is fixed in version 5. Why are timestamps on extracted files sometimes off by an hour under Windows. 4 Zip was unable to allocate sufficient memory to complete the command. , don’t delete it. 51 The end of the ZIP archive was encountered prematurely. (Thanks to Anya Berdichevskaya for the pointer. 2 The zipfile is either truncated or damaged in some way (e. You can still test, update and delete entries from the archive; it’s a fully functional zipfile. Note that it applies only to our more recent releases (starting in November 1999): Zip 2. Short answer: because that’s how they’re stored in the zipfile, and backslashes (”) are regular filename characters, not directory separators. Some file systems and/or C libraries may not support files this big, however, and there are other zipfile limits (see below) that may have an impact. 3 The structure of the zipfile is invalid; for example, it may have been corrupted by a text-mode (“ASCII”) transfer. 9 The specified zipfile(s) was not found. COM file: $ unzip == “$disk:[dir]unzip. Don’t send us “bug reports” about it. How do I extract Windows 95/98 long filenames (VFAT) under plain DOS. Processing may have completed successfully anyway; some broken zipfiles created by other archivers have simple work-arounds. Because the bug is located in the output routine after the CRC check has been carried out (because there isn’t any way to know the CRC for the text-converted data), it is not detected by any built-in consistency check. 14 Zip encountered an error writing to an output file (typically the archive); for example, the disk may be full. Can I use the Windows DLLs in a multithreaded application. This has now been confirmed to be a long-standing bug in Zip itself (within zipup. If an archived file was last modified during Daylight Savings Time (a. Return to the Info-ZIP Home Page. Tigchelaar’s LDZIP can be used to back up long filenames under plain DOS. 0 and UnZip 6. 04, and subsequent updates. 2 will happily store more than 64K files (we’ve tested with 70,001); UnZip 5. These include its weak encryption, poorly designed “extra field” capability, poorly designed “multi-disk” support, mediocre robustness, support for streaming encoders only as an afterthought, low-precision timestamps (two-second granularity), lack of cross-timezone support (i. So the public statements were, most likely, simply the usual legal posturing. Creating zipfiles on NFS file systems under Red Hat 6. , not just the 26 lowercase letters), it might still be recoverable via a known-plaintext attack (see above). (Note that DOS 7. Here’s an example showing how it works (which also ties in to the previous question). We believe this bug affects all previous versions of UnZip, as well, and most or all supported platforms. Symantec’s Norton AntiVirus reports that your DOS executables are infected with WEED. It does not affect files that are stored due to small size or incompressibility; these files use the code path in deflate. (Note that the more common 32-bit and 64-bit UnZip ports are not affected. ) Zip (all

It works fine in a Win9x DOS window, but I want to be able to restore a backed-up Win9x system from scratch. 50 have a symlink-traversal vulnerability whereby extracted files can overwrite files in unexpected directories if appropriate directory-symlinks are extracted first. Imran Ghory reported that the Unix port of UnZip has a race-condition vulnerability (CAN-2005-2475), whereby a local attacker could change the permissions of the user’s files during unpacking. 4 UnZip was unable to allocate memory for one or more buffers during program initialization. There was some bug involving updating archives (-u and -f options) on a networked HPFS386 partition, wherein part of the zipfile would be filled with zeros instead of the actual compressed data and header info. According to strict interpretation of the 2. ) Zip 2. And writing very low-level, OS-dependent code to support one system violates Info-ZIP’s goal of maximal portability (even if most of the necessary code is already freely available in Linux and elsewhere, though possibly with incompatible licenses). On VMS, both UnZip’s and Zip’s error codes are translated into a range appropriate to VMS. 51 related to very long (command-line) zipfile names, which theoretically could lead to local privilege escalation (e. ) compressed size of a single file 4 GB In practice, the real limit may be 2 GB on many systems, due to UnZip’s use of the fseek() function to jump around within an archive. Watch these web pages, subscribe to the mailing list(s), and/or check the freshmeat pages for news. The Info-ZIP group has not explicitly tested any compilers for such problems. For example, return code 5 becomes 0x7fff0000 + 16*5 + 4 = 0x7fff0054 = 2147418196. ” sequence that is used without further checks during extraction. ) Are there any known file-corruption, data-loss, or security bugs in Zip or UnZip. They are defined as follows: Zip value meaning 0 Normal; no errors or warnings detected. For archiving only (i. How can I rename zipfile members without extracting and recompressing them. , 128 years after 1 January 1980) and Unix-format dates where available (no problems until January 2038, when 231 seconds will have elapsed since 1 January 1970). Processing probably failed immediately. Hardin for reporting this. You don’t pay for the code; don’t expect us to do so, either. ) apply to zipfiles. The passwords for my encrypted zipfiles don’t work on HP-UX. 2 @ (comment above this line) @ invalidothersubdiroldname. You may or may not be hosed. The “$” before the disk name is important; i. 50
and earlier all All versions of UnZip through 5. ) Thus, by default, unshrinking was not enabled in some releases of Info-ZIP’s distributed binaries (mostly newer ones). This is because UnZip uses the zipfile’s central directory for listing files (and for matching user-specified filenames for extraction), but it uses the local file headers during the actual extraction process itself. , Universal Time) except as a third-party add-on, lack of any support for “solid” packing of small files, lack of support for alternate character sets (e. 1 or later is required to support the newer FAT32 partitions. The documented method doesn’t work. ) maximum path/filename length 64 KB Zipfiles have essentially no limits on the length of pathnames (or on the depth of directory trees); the actual limits will be imposed by the file system on which the archive was created. ZipNote has provided this capability almost since it was created, but the interface is very crude and not necessarily as well documented as it should be. This includes zipfiles where one or more files was skipped due to unsupported compression method or encryption with an unknown password. 50 comments below), the following limits apply to all zipfile archives: statistic limit comments number of files 65,536 This is not a “hard” limit, and Zip 2. This will allow the utilities to handle uncompressed data files greater than 2 GB in size, as long as the total size of the archive containing them is less than 2 GB. 10 Zip encountered an error creating or using a temporary file. C only, not deflate. The “shrink” compression method was encumbered by a patent (“LZW”) until July 2004. Why does my VMS UnZip say “too many parameters” and do nothing but print the usage screen for me. 1 had a -t option that was not Y2K-ized, but that was fixed in 2. 3 @ (comment above this line) @ (zip file comment below this line) Next, edit the output file–but in place of file comments, add lines specifying new filenames, using the special “@=” syntax: @ invalidsubdiroldname. What do the error codes mean. If someone else did, you should ask them to upgrade.

How to unzip multiple ziped files and rename automatically if needed. Unzip file with underscore in linux.

What do you do. You can use netcat as a makeshift file transfer software. Let’s say you want to transfer a big zip file from machine A to machine B but neither one has FTP, and using email or IM is out of the question due to file size, or other restrictions.

2 @ (comment above this line) @ invalidothersubdiroldname. 82 No files were found due to bad decryption password(s). Total size of archive 256 TB While the only theoretical limit on the size of an archive is given by (65,536 files x 4 GB each), realistically UnZip’s random-access operation and (partial) dependence on the stored compressed-size values limits the total size to something in the neighborhood of 2 to 4 GB. And on 64-bit systems, UnZip won’t find any file that’s more than 4 GB from the beginning (since the zipfile format can only store offsets that big). , 1024-character maximum path length, a list of invalid filename characters, etc. 10 Zip encountered an error creating or using a temporary file. Once the noise level exceeded the convenience factor, it had to go. Why are encrypting versions of Zip not distributed from your main site. It affected many archivers and other programs, and it could be fixed only by patching the NFS server. Can I use the Windows DLLs in a multithreaded application. Exe // doesn’t recurse as expected For now, the previous method (using -r and -i) will work. This is fixed in version 2. 04, and subsequent updates. They are defined as follows: Zip value meaning 0 Normal; no errors or warnings detected. Why do files with extended attributes get extracted under OS/2 with the current time while all other files retain their original timestamps as expected. That’s wrong. 8 Testing (-T option) failed due to errors in the archive, insufficient memory to spawn UnZip, or inability to find UnZip. The standard version 5. This table was created in August 2001 and last updated in May 2005. 50 have a pair of directory-traversal vulnerabilities, both somewhat subtler than the original one (see above). This is fixed in version 5. When you’re done editing the output file, use ZipNote once more to apply it to the zipfile. For example: unzip -t foo. Plain DOS, even the DOS 7. But compiled binaries that included encryption (as opposed to decryption-only) were still restricted, so our main US distribution site continued to carry only non-encrypting Zip binaries. However, we do have a report that a user of the Win32 versions of Zip and UnZip succeeded in compressing and extracting a 7 GB database file. ” This can be ignored. Finally, run UnZip just as on any other system (see FAQ #2). You can still test, update and delete entries from the archive; it’s a fully functional zipfile. C with optimization turned off (no -O or +O2 option) or turned down to the lowest level (+O1). ] and the shell itself [bash, tcsh, etc. Some CD-ROM file systems have an 8-level subdirectory limit. (If even one file is successfully processed, however, the exit status is 1. (It may also affect other tools, including some shells and gdb itself. Ordinarily the local and central filenames match, but an attacker could modify the names (and paths) in the local headers in order to cause files to be created in unexpected locations. Since we depend on others to provide binaries for many of the less-common architectures, and since some of those have not been updated since the restrictions were lifted, not all of our binaries support encryption. This includes zipfiles where one or more files was skipped due to unsupported compression method or encryption with an unknown password. (For what it’s worth, the same algorithm was and is used in other utilities that have been included in every Linux and FreeBSD distribution that has ever shipped or been downloaded, and no one has ever complained about that. So far these headers are undocumented, but most of their fields are fairly obvious. 4; check UnZip with “unzip -v”). Because the bug is located in the output routine after the CRC check has been carried out (because there isn’t any way to know the CRC for the text-converted data), it is not detected by any built-in consistency check. 3 all When compiled with either BIG_MEM or MMAP defined (MMAP overrides BIG_MEM if both are defined), Zip will silently corrupt stored (uncompressed) files when forced via either the -0 (“store”) or -n (“don’t compress these suffixes”) options. Exe // create the SFX archive zip -A yourDOSzip. This is fixed in version 2. Here’s an example showing how it works (which also ties in to the previous question). Hhmmss format (unzip -ZT) for sorting, if you wish. The first one (CVE-2003-0282) involves placing one or more invalid characters between a pair of dots; the bogus characters are filtered out, leaving a “. Older versions (5. Windows Chad Loder of Rapid7 discovered a crash bug and potential security vulnerability in WiZ, involving very long filenames inside archives. This is a known bug with HPFS386-based network drives (LAN Server 4. All older releases are still covered by our old COPYING file (UnZip) or the README file in official Zip distributions. On VMS, both UnZip’s and Zip’s error codes are translated into a range appropriate to VMS. Yup, there are recursion bugs in the Win32 port of both Zip 2. , Universal Time) except as a third-party add-on, lack of any support for “solid” packing of small files, lack of support for alternate character sets (e. ), as described above; we’ll assume DOS in the following example. There are no particular limits on zipfile filenames when renaming with ZipNote (other than the 65,535-character limit on filename lengths), but note that the target filesystem may have much more stringent limits (e. 0 of Norton AV (for Windows 95/98) does not report any such thing. , not just the 26 lowercase letters), it might still be recoverable via a known-plaintext attack (see above). If it was more than 8 or 10 characters and not restricted to a small subset of ASCII (e. 0 are coming along and should be released sometime in the first half of 2007. No–unless UnZip is compiled with USE_ZLIB defined and the relevant version of zlib has the bug (i. 41 and later will extract them again. 4x series should be completely fixed. ) Thus, by default, unshrinking was not enabled in some releases of Info-ZIP’s distributed binaries (mostly newer ones). ) 6 ZipSplit was unable to create an archive of the specified size because the compressed size of a single included file is larger than the requested size. 2 A generic error in the zipfile format was detected. X], and possibly other file utilities [ls, rm, etc. 2 will happily store more than 64K files (we’ve tested with 70,001); UnZip 5. See UnZip’s COPYING and INSTALL files for more information. After successful extraction, read the enclosed unzip. Thanks to Joe Forster, Bruno Binet and Jim O’Dell for the tip. (There may still be errors in the archive, but if so, they weren’t particularly relevant to UnZip’s processing and are presumably quite minor. (Thanks to Anya Berdichevskaya for the pointer. 3 @ (comment above this line) @ (zip file comment below this line) Next, edit the output file–but in place of file comments, add lines specifying new filenames, using the special “@=” syntax: @ invalidsubdiroldname. 1 or later is required to support the newer FAT32 partitions. Because the stored CRC-32 value is consistent with the corrupted data, testing with UnZip will not expose the error; only extraction and byte-for-byte comparison with the original files will. 1 @ (comment above this line) @ invalidsubdiroldname. (Thanks to jelmer and ITO Tsuyoshi for reporting them. How can I recover my data. 80 The user aborted UnZip prematurely with control-C (or similar) 81 Testing or extraction of one or more files failed due to unsupported compression methods or unsupported decryption. Deutscher for reporting this bug and Christian Spieler for identifying it in the source code. See the next item for more information about that. The second involves the use of a quoted “/” character, which could be used either to convert a harmless “. 20 that breaks Zip’s encryption code and UnZip’s decryption code. ) directory-traversal variant. ) We addressed this problem in 1997 for UnZip 5. 1 had a -t option that was not Y2K-ized, but that was fixed in 2. Thus any of the following workarounds will suffice: never use the -0 or -n options always use the -9 (“maximal compression”) option, which overrides -0 and -n use the default compilation options, in which neither BIG_MEM nor MMAP is defined Note that there are some systems that appear to be immune to the bug, including DEC/Compaq systems with the DEC/Compaq C compiler (but not with the GNU C compiler). Why does WiZ say “Failure creating property sheet” when I pick the Options menu item. Web page maintained by Greg Roelofs. How do I extract one. 0 or later. Zip // under Unix Then use Zip’s “zipfix” option to patch up the big archive (optionally get rid of all of the little pieces first if you’re short on disk space): zip -F monster. ” sequence into a harmful one or to create absolute (leading-“/”) paths. 14 Zip encountered an error writing to an output file (typically the archive); for example, the disk may be full. ” sequence that is used without further checks during extraction. How to Use How do I use UnZip. ) UnZip 5. , the latter cannot be decoded on other systems). X OS/2 3. ) Zip (all
versions) Solaris, AIX,
Red Hat Linux,
others. The double-free bug affected only the version of inflate() in zlib; UnZip’s version is not vulnerable, and Zip does not use inflate(). Compression FAQ list is the place to start looking. 50, and a patch (slight overkill, but apparently effective) is available on the Bugtraq page that reported the problem. We don’t yet know when Zip and UnZip will support this extension to the format. You also have the option of displaying dates in yyyymmdd. (On 64-bit IRIX with the native compiler, the options “-mips4 -64” or “-mips4 -64 -ipa” [for both compiling and linking] may help. 3 and earlier, possibly also 5. ) Are there any known file-corruption, data-loss, or security bugs in Zip or UnZip. 16 The command-line parameters were specified incorrectly. First grab the appropriate UnZip binary distribution for your target platform (DOS, Windows, OS/2, etc. We don’t recall the exact details, but an OS/2 fixpak is/was available to take care of the problem. The “shrink” compression method was encumbered by a patent (“LZW”) until July 2004. Do you support multi-volume archives. We believe the statements above to be completely truthful and accurate, but we accept no liability for errors in either the statements or the software. (You may wish to do this to a copy of the archive, just in case something goes wrong. The UnZip DLL is believed to be thread-safe. To check what compiler was used to create any of our pre-compiled executables, do “unzip -v” or “zip -v” with no other arguments. Although it appeared that standalone unshrinking was not covered, the owner claimed otherwise in public statements, and the matter was never tested in court. COM file: $ unzip == “$disk:[dir]unzip. X zipfile specification (but see the PKZIP 4. For archiving only (i. See also Secunia’s advisory. This is not yet supported by UnZipSFX. Tigchelaar’s LDZIP can be used to back up long filenames under plain DOS. 3 A severe error in the zipfile format was detected. This is fixed in version 5. 51 The end of the ZIP archive was encountered prematurely. 9 Zip was interrupted by user (or superuser) action. 5 Internal logic error. Either way, the comp. This is almost certainly an error in the Symantec “emergency boot disk,” which, according to a Symantec response on their German web site, has an outdated virus signature file. 50
and earlier Unix, BeOS,
Atari, AOS/VS All versions of UnZip through 5. Info-ZIP’s utilities use the normal C library functions to read and write files; those functions, in turn, depend on the operating system to provide file-system support. It works fine in a Win9x DOS window, but I want to be able to restore a backed-up Win9x system from scratch. UnZip’s error codes are documented in its man(ual) page, unzip. Where “disk” and “dir” refer to the true disk and directory where unzip. ), it will support long filenames under Windows 95/98/ME (not NT/2000) or short filenames under plain DOS. )   UnZip 5. 1 is this: zip -r foo. 0 (success) is translated to 1 (VMS success), and all others are multiplied by 16 and added to 0x7fff0000 plus a final offset of 0, 2 or 4 depending on whether the return code is a warning, a “normal” error, or a severe (fatal) error, respectively. How do I create a self-extracting archive that will automatically run a program after extraction. This results in an off-by-one-hour problem in some extracted files, especially around April and October when locales that observe DST typically switch between it and Standard Time. Then extract the UnZipSFX stub from the distribution and prepend as if it were a native Unix stub: unzip unz552x3. Internally it uses DOS-format dates by default (no problems until 2108; i. ) How do I make the Win32 version (32-bit Windows) of Zip 2. 31) would print “100” instead of “00” for the year 2000; this is fixed in 5. 11 No matching files were found. Can I use the Windows DLLs with Visual BASIC. Many thanks to Michael Kilby for tracking this down. VMS file included with our VMS distributions. 51 related to very long (command-line) zipfile names, which theoretically could lead to local privilege escalation (e. You may or may not be hosed. You don’t pay for the code; don’t expect us to do so, either. 50
and earlier all All versions of UnZip through 5. ) compressed size of a single file 4 GB In practice, the real limit may be 2 GB on many systems, due to UnZip’s use of the fseek() function to jump around within an archive. 3 The structure of the zipfile is invalid; for example, it may have been corrupted by a text-mode (“ASCII”) transfer. Newer versions of WinZip correct that bug, so if you created the archive in question, you should upgrade. ] if redirection is involved. 2 The zipfile is either truncated or damaged in some way (e. Two reasons: you’re using an old version of UnZip (5. These are fixed in version 5. 50
and earlier virtually all All versions of UnZip through 5. According to strict interpretation of the 2. Miscellaneous When are the next versions of Zip and UnZip coming out. 0, which will once again enable unshrinking by default. In effect, this is yet another (fourth. Note, however, that ZipNote does make a temporary copy of the zipfile while working (in case it’s interrupted), so you will briefly need room for the extra temporary copy in addition to any copy you may have made. ) How do I report bugs. ), using whatever command is appropriate for your system: copy/b part1. The -R bug is fixed in 2. (Note that the more common 32-bit and 64-bit UnZip ports are not affected. (The older forum at QuickTopic is also available in read-only mode; click the “printer-friendly” link to see the archived, non-spam messages in compact form. 2, but that version in turn has a bug in its new -R option: zip -R foo. 7 UnZip was unable to allocate memory during in-memory decompression. For example, return code 5 becomes 0x7fff0000 + 16*5 + 4 = 0x7fff0054 = 2147418196. ) Also note that in August 2001, PKWARE released PKZIP 4. The documented way in 2. 5 UnZip was unable to allocate memory or unable to obtain a tty (terminal) to read the decryption password(s). This will allow the utilities to handle uncompressed data files greater than 2 GB in size, as long as the total size of the archive containing them is less than 2 GB. ) Extraction is currently supported, however, albeit in a crude manner. This restriction may be relaxed in a future release. Note that paths specified as arguments must be in zipfile format–that is, forward slashes (“/”), no drive letters, etc. 0 or Warp Server), and IBM has not provided a patch. UnZip displays only two digits of the year when listing files (in most formats), so if you take that output and sort on the year field, it will fail. This is fixed in version 5. Look for UnZip 6. You need to upgrade your copy of Internet Explorer to version 4. 12 There was nothing for Zip to do (e. There is no capability in Unix UnZip to treat backslashes as directory separators (since they’re perfectly acceptable filename characters, just like colons, quotes, and pretty much everything other than forward slashes), so if you want to extract the archive as a subdirectory tree without hacking the source code, you’ll need to rename the archive entries. Txt (which is included with all official distributions), and are defined as follows (on all platforms but VMS): UnZip value meaning 0 Normal; no errors or warnings detected. ) Zip 2. 50 have a filename-mismatch vulnerability whereby files can be extracted with paths and names other than those that appear in archive listings. ) One workaround is to “ensure that any directory which is being used by unzip to decompress files is writeable only by the user”; another is to “set the sticky bit on the directory’s permissions. ) UnZip 5. There was some bug involving updating archives (-u and -f options) on a networked HPFS386 partition, wherein part of the zipfile would be filled with zeros instead of the actual compressed data and header info. Processing probably failed immediately. First, redirect ZipNote’s output to a file that you can subsequently edit: zipnote invalid-dirseps. Exe // archive to the current directory This can be done either from a command-line prompt or via a “Run This” menu item (e. That’s at the top of the to-do list, however. Txt file for explicit directions on using the newly extracted unzip. In January 2000, the Bureau of Export Administration (BXA) of the US Department of Commerce relaxed its restrictions on the export of free encryption source code, so newer Info-ZIP releases do now include the full crypto sources. ) maximum path/filename length 64 KB Zipfiles have essentially no limits on the length of pathnames (or on the depth of directory trees); the actual limits will be imposed by the file system on which the archive was created. We believe this bug affects all previous versions of UnZip, as well, and most or all supported platforms. Are Info-ZIP tools affected by the zlib double-free security vulnerability. Yes, at least the UnZip 5. Exe” $ zipinfo == “$disk:[dir]unzip. 0 and UnZip 6. 9 The specified zipfile(s) was not found. , in the case of automated, UnZip-based unpacking of user-specified archive names by a privileged account–not a terribly likely scenario). This is fixed in version 2. 3
and earlier all HexView reported a buffer-overrun vulnerability (CVE-2004-1010) in Zip 2. So while Info-ZIP’s Win32 versions do support long filenames in Win9x DOS boxes, they don’t even run under plain DOS. All of these things suggest that it’s time for a brand-new format, not just a few more patches on an aging standard. Exe // extract the DOS SFX stub cat unzipsfx. So the public statements were, most likely, simply the usual legal posturing. The documented method doesn’t work. The Info-ZIP group has not explicitly tested any compilers for such problems. ) Zip-Bugs, the internal mailing list for the core development team, was shut down in August 2003 in favor of a web-based contact form. (The only reported oddity was in listing the archive’s contents; UnZip has no way to know that the true file size is bigger than what the zipfile directory reports. On the other hand, Info-ZIP had no particular desire to become the test case. Zip // test the archive “foo. (Adding functionality to run a custom install program is pretty simple, however; grab the sources and roll your own. ) generally limit paths to 256 characters or less; Unix systems typically have a 1024-character limit. , bogus internal offsets) that makes it appear to be truncated. 50 The disk is (or was) full during extraction. Zip” (see // unzip. Specifically, if an archive contains files with leading “/” characters (i. 1 @ (comment above this line) @ invalidsubdiroldname. 18 Zip could not open a specified file for reading; either it doesn’t exist or the user running Zip doesn’t have permission to read it. How can I rename zipfile members without extracting and recompressing them. (What happened to the Zip-Bugs address. 42 have a directory-traversal security vulnerability that allows them to unpack files in unexpected places. 50 with support for large files and archives via a pair of new header types, “PKx06x06” and “PKx06x07″. Because’s fseek’s offset argument is usually a signed long integer, on 32-bit systems UnZip will not find any file that is more than 2 GB from the beginning of the archive. 1’s -y option, symbolic links got stored as empty files–i. 4 Zip was unable to allocate sufficient memory to complete the command. There have been a few over the years. All file times will appear to shift by an hour. (The operating system also must have support for large files; for Linux, this involves the kernel [2. Exe // recursively archive all *. (This was not a Zip bug, per se. ) Can I expect any Y2K problems. ” This will be fixed in version 6. Last updated 4 October 2008. Please direct all Info-ZIP queries (availability, ports, bugs, corrections, etc. Txt for other examples) Note that currently all but three ports are command-line only. 1 and 2. I forgot the password on my archive. For self-extracting archives such as the one used in the example above, simply copy or move it into the directory of your choice, cd into that directory and run the self-extracting archive: unz552xN // extract contents of unz552xN. To our knowledge, this has not yet happened. Note that it’s possible that some PC-based C compilers or libraries have Y2K bugs in them that would affect Zip and UnZip. 2 will emit a warning about a “preamble of xxx bytes. UnZip (and Zip, and all of the other Info-ZIP utilities) must be set up as a VMS foreign command, as noted in the README. And the DOS versions mostly don’t support long filenames, with one exception: if UnZip is compiled with the free djgpp 2. , not extracting), J. But since you asked: It depends a bit on how you use Zip and UnZip, but by and large there shouldn’t be any problems. This is fixed in version 5. Zip // under DOS, OS/2 or Win* cat part1. ) This is fixed in version 5. Those who wish to download older binaries or compile their own versions may still do so, or you can wait for UnZip 6. Where can I get a Mac version of Zip. Your web page says (used to say) Jet Propeller Laboratory. ) UnZip 5. (Earlier releases will not. Other possibilities include Duncan Murdoch’s DOSLFNBK and LFNSORT utilities. 2 recurse through subdirectories and archive only files matching a certain pattern. 00 for platforms that have the fchmod() system call. The currently available 32-bit executable in unz552x3. Also note that 16-bit DOS versions of Zip are limited to around 16,000 files. All of the quotes in the ZipInfo line are necessary, too, so don’t delete any of them, either. Can I use the Zip or UnZip source code or executables in my commercial product. Common Problems Why does UnZip say “‘shrink’ method not supported”. However, in June 2002, the newly renamed Bureau of Industry and Security (BIS, still part of the US Department of Commerce) further relaxed its restrictions on the export of object code compiled from free encryption source code. ) zipnote -w copy-of-invalid-dirseps. 0 at the heart of Windows 9x, does not support VFAT or FAT32 long filenames. 11 Reading or seeking (jumping) within an input file failed. That said, as of mid-2006, Zip 3. X compiler (now part of Cygwin. Imran Ghory reported that the Unix port of UnZip has a race-condition vulnerability (CAN-2005-2475), whereby a local attacker could change the permissions of the user’s files during unpacking. Don’t send us “bug reports” about it. Hardin for reporting this. If the archive doesn’t run, either you don’t have enough memory available (try exiting to plain DOS if running a graphical shell) or you didn’t download the archive properly (see FAQ #1). ) The workaround is to disable 64-bit deflate support when compiling 16-bit UnZip ports (define NO_DEFLATE64). The three exceptions are the Macintosh port (MacZip, with integrated Zip support), the Windows 3. ) How do I make a DOS (or other non-native) self-extracting archive under Unix. Exe files This bug was fixed in Zip 2. 0 someday, but no more promises as to when. (Actually, the whole zipfile format is showing its age; arguably it would be better to start over from scratch than to retrofit support for PKWARE’s broken multi-part scheme onto the existing code base, but that’s even more work. In the short term, it is possible to improve Zip and UnZip’s capabilities slightly on certain Linux systems (and probably other Unix-like systems) by recompiling with the -DLARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64 options. The root cause is a longstanding bug in Windows NT, Windows 95/98, and Windows CE. If the password was very short (i. , essentially useless), there are various brute-force password-crackers available. 4 DLLs and Zip 2. ) Zip’s error codes (and those of ZipSplit, ZipNote, and ZipCloak) are documented only in the ziperr. , relative to the top-level/root directory) or with “. 12 or earlier); you’re extracting to an HPFS386-based drive. 2 and seems to have been the only problem. Txt // create renaming template ZipNote’s output (in invalid-dirseps. Archive Limits and Known Vulnerabilities What limits (number of files, size of files, etc. This problem does not appear to affect any of Info-ZIP’s command-line tools or MacZip. Summer Time) and is being extracted during Standard Time–or vice versa–Windows applies the current timezone offset (including DST) to the extracted file instead of using the offset that was applicable on the date the file was created or otherwise modified. 10 Invalid options were specified on the command line. MacZip, a Macintosh port by Dirk Haase that includes both Zip and UnZip capability, was officially released in January 2000 and is available in both source and binary forms. ” components (“previous directory level”), UnZip will unpack the files in the indicated locations, possibly creating directory trees in the process–and, if the -o (“overwrite”) option is given, quietly destroying existing files outside the intended directory tree. Exe // doesn’t recurse as expected under Windows 9x, NT This is what actually works: zip -r foo. Exe // fix up internal offsets That’s it. 2 @ (comment above this line) @ invalidothersubdiroldname. We apologize for the inconvenience. (Thanks to Jan Echternach for reporting this. We may set up new lists on SourceForge at some point, but in the interim, a web-based forum, with both bug-reporting and discussion areas, has been set up. This is because UnZip uses the zipfile’s central directory for listing files (and for matching user-specified filenames for extraction), but it uses the local file headers during the actual extraction process itself. 51
and earlier Unix only Albert Puigsech Galicia noted that one of UnZip’s backup-related features, the restoration of file permissions including UID and GID bits, could constitute a privilege-escalation vulnerability (CVE-2005-0602) insofar as (1) UnZip doesn’t emit a warning when restoring such bits, and (2) it’s the default behavior in version 5. The procedure is basically described in the UnZipSFX man page. The “$” before the disk name is important; i. Why does my VMS UnZip say “too many parameters” and do nothing but print the usage screen for me. There is an optimization bug in the native (non-GNU) HP C compiler for HP-UX 10. It may be supported in a future release, but no promises. Note that Zip versions prior to 2. What do the error codes mean. X/9x/NT port (WiZ, also with integrated Zip support), and the Windows CE/NT port (Pocket UnZip). Uncompressed size of a single file 4 GB This is also not a hard limit, in that the deflate algorithm used in all recent releases has its own “end of stream” marker. ) Why does my Unix UnZip extract flat filenames with backslashes in them instead of a subdirectory tree. 50 16-bit ports
(e. ZipNote has provided this capability almost since it was created, but the interface is very crude and not necessarily as well documented as it should be. 3 related to deep directory paths, which could potentially lead to local privilege escalation (e. 15 Zip could not open an output file (typically the archive) for writing. Exe was compiled with djgpp 2. (Thanks to Mark Adler for verifying this. These include its weak encryption, poorly designed “extra field” capability, poorly designed “multi-disk” support, mediocre robustness, support for streaming encoders only as an afterthought, low-precision timestamps (two-second granularity), lack of cross-timezone support (i. See Rapid7’s advisory for test archives and subsequent links, including CERT and CVE. 6 UnZip was unable to allocate memory during decompression to disk. (This should never happen; it indicates a programming error of some sort. ) apply to zipfiles. , HPFS-Access, Amos, etc. Alas, we’re really slow and still don’t support the creation of multi-volume (or multi-disk) archives. 42
and earlier virtually all All versions of UnZip through 5. Short answer: because that’s how they’re stored in the zipfile, and backslashes (”) are regular filename characters, not directory separators. Why are timestamps on extracted files sometimes off by an hour under Windows. The passwords for my encrypted zipfiles don’t work on HP-UX. Txt) will look something like this: @ invalidsubdiroldname. Note that there are other limitations of the zipfile format beyond its dependence on 16-bit and 32-bit fields. 0 and Zip 3. If an archived file was last modified during Daylight Savings Time (a. , UTF-8), unnecessary redundancy, and merely acceptable (but no longer outstanding) compression efficiency. 1 any Unix With Zip 2. X could result in silent corruption. 50 have a symlink-traversal vulnerability whereby extracted files can overwrite files in unexpected directories if appropriate directory-symlinks are extracted first. Finally, note that this is not a warranty or certification of Y2K readiness. ) Finally, note that the original encryption scheme used in all versions of Zip (as well as PKWARE’s older products) is quite weak; see “A Known-Plaintext Attack on the PKZIP Stream Cipher” (also as gzip’d PostScript) by Eli Biham and Paul C. This was a known bug in Solaris (Sunsolve ID 4071076), AIX (IBM APAR IY06322) and possibly other Unixen that seems to have been exacerbated by Red Hat’s knfsd. 3, and while there may have been some lingering oversights in that series, the UnZip 5. Recent versions of PKZIP and WinZip include stronger AES encryption, and PGP/GnuPG have provided strong encryption for many years. (Note that DOS 7. Processing may have completed successfully anyway; some broken zipfiles created by other archivers have simple work-arounds. See our new(er) open-source, BSD-style license for details. , in the case of automated, Zip-based backups by a privileged account). We currently have no plans to do a WinCE port of Zip. 4 or later], the file system [at least Reiser and ext2 are supported], the C library [glibc 2. How do I extract Windows 95/98 long filenames (VFAT) under plain DOS. (Aside: You can see the bug in action, completely independent of Zip and UnZip, by saving a Windows directory listing just before the switch and comparing it with one taken just after the switch. ) 1 One or more warning errors were encountered, but processing completed successfully anyway. This is fixed in version 5. As convenient as the real e-mail address was to everyone involved, it turned out to be equally convenient to the masses of header-forging viruses and spam messages propagating across the Internet. 2 and later have a work-around for the problem, however. , any version of zlib before 1. Txt // rename zipfile filenames That’s it–no recompression required. Where can I get a Windows CE version of Zip. Your best bet, therefore, is to try Chris Jones’ LFNDOS VFAT/FAT32 device driver for DOS, which is somewhat similar to the OS/2 HPFS device drivers already available for DOS (e. 3) and one subdirectory name (othersubdir), and lengthens one filename (oldname. Longer answer: older versions of WinZip (and, no doubt, some other clone zippers) stored filenames using backslashes as directory separators in violation of PKWARE’s appnote, which specifies that forward slashes (‘/’) should be used. Note that it applies only to our more recent releases (starting in November 1999): Zip 2. We didn’t have one. , DOS) For all ports using 16-bit integers, textmode output (-a or -aa options) is broken in such a way that half of the output-buffer chunks are silently skipped. Don’t hold your breath, eh. , 128 years after 1 January 1980) and Unix-format dates where available (no problems until January 2038, when 231 seconds will have elapsed since 1 January 1970). 51
and earlier all c0ntex reported a buffer-overrun vulnerability (CVE-2005-4667) in UnZip 5. 3 @ (comment above this line) @ (zip file comment below this line) Note that this particular example changes all backslashes to forward slashes, shortens two filenames (oldname. (Thanks to Jan Echternach and John D. The Zip DLL is not. (If you have the ability to compile a newer version than what we currently provide, please contact us. (Note that Zip and ZipSplit still do not support the creation of PKWARE-style multi-part archives. Do not type “run” before the command. ) UnZip 5. And writing very low-level, OS-dependent code to support one system violates Info-ZIP’s goal of maximal portability (even if most of the necessary code is already freely available in Linux and elsewhere, though possibly with incompatible licenses). It is probably not 100% complete (particularly with respect to very old bugs), but it’s close: program platform nature of bug Zip 2. Note that this bug affects both decryption of zipfiles created elsewhere and encryption of zipfiles created on HP-UX (i. It’s a bit late to be worrying about that now. Add some lines similar to the following to your LOGIN. 4 UnZip was unable to allocate memory for one or more buffers during program initialization. We have not tested it ourselves, but it sounds like it does exactly what’s needed.   WiZ 5. This has now been confirmed to be a long-standing bug in Zip itself (within zipup. Creating zipfiles on NFS file systems under Red Hat 6. “-ipa” is reported to generate incorrect code sometimes, however. First concatenate all of the pieces together (in order. 52: the new -K option must be given explicitly in order to restore UID, GID and sticky bits. ) 7 The format of a zipfile comment was invalid. 3 DLLs (and later versions). ) Note that Zip will first store in memory the path/filename and various parameters for every file that will be in the final archive; the actual limit on the number of files may be determined by the amount of RAM and/or virtual memory available on the system. Yes, this is a fifth directory-traversal variant. C only, not deflate. Some file systems and/or C libraries may not support files this big, however, and there are other zipfile limits (see below) that may have an impact. DOS and its derivatives (Windows, OS/2, etc. (Note that the same bug will affect any program that uses the DosSetPathInfo() call. There is a bug in older versions. So the last file in the archive can potentially be arbitrarily large (in theory, anyway–we haven’t tested this), but the combined total of all the rest must be less than 2 GB or 4 GB, respectively. 50 comments below), the following limits apply to all zipfile archives: statistic limit comments number of files 65,536 This is not a “hard” limit, and Zip 2. If someone else did, you should ask them to upgrade. This is fixed in version 5. (Thanks to Stefan A. The encryption key in Zip is 96 bits long, which originally required an export license to export from the US, even though the encryption code was imported into the US in the first place. Symantec’s Norton AntiVirus reports that your DOS executables are infected with WEED. Contacting Info-ZIP Do you have any mailing lists for discussions. However, if and when the Windows bug is ever fixed, it’s possible that Info-ZIP’s workaround will recreate the bug in reverse. Copyright © 1995-2008 Greg Roelofs. So ever since June 2003 (when we sent in our required export notification), we have distributed full encryption/decryption binaries along with the full source code–when we had them in the first place. Zip // fix up the concatenated archive The archive is now a large but perfectly ordinary zipfile (unless it’s bigger than 2 GB, in which case see below); extract, test or list its contents just like you normally would. It does not affect files that are stored due to small size or incompressibility; these files use the code path in deflate. , all knowledge of the file to which the link pointed was lost within the archive. We believe this bug affects all previous versions of Zip, as well, and most or all supported platforms. 13 The zipfile was missing or empty (typically when updating or freshening).

Once the noise level exceeded the convenience factor, it had to go.

But compiled binaries that included encryption (as opposed to decryption-only) were still restricted, so our main US distribution site continued to carry only non-encrypting Zip binaries. In January 2000, the Bureau of Export Administration (BXA) of the US Department of Commerce relaxed its restrictions on the export of free encryption source code, so newer Info-ZIP releases do now include the full crypto sources.
