While having a physically local attacker being able to cause your machines to crash without touching them is bad, but it’s certainly not as bad as remote root. With a kernel compiled in this way, the flaw turns from remote code execution to a remote crash (kernel panic). Stack Protection has been available for some time, having been introduced in some distributions back in 2005. We believe most major vendor distributions build their Linux kernels with Stack Protection enabled. For us, this includes Fedora Core (since version 5) and Red Hat Enterprise Linux (since version 6).

The success of Red Hat performance-based certifications stems from a solid track record of benchmarking and hands-on skills assessment.

Technical Resume

Nonetheless, we would like to recommend software engineers working on RHEL to no longer rely on SHA-1 for cryptographic purposes, and system administrators to verify that they no longer use certificates, OCSP stapled responses, or any other cryptographic structure with SHA-1 based signatures. We do not yet plan to disable SHA-1 system-wide in RHEL 7 as a significant amount of infrastructure still depends on it, and disabling it would severely disrupt operations.

CVE-2016-7050 took advantage of the deserialization capabilities of SerializableProvider. Luckily, the RESTEasy version used in the supported version of JBoss EAP 7 was later than 3. Final, so it was not affected. It was reported to Red Hat by Mikhail Egorov of Odin. It was fixed upstream1 before Product Security became aware of it.

When a new Red Hat Enterprise Linux minor version update is released then the aligned Red Hat Virtualization Hypervisor build supersedes the previous versions. Red Hat Virtualization Hypervisor versioning is aligned with the Red Hat Enterprise Linux version that it is based on.

This article describes how to use tlsfuzzer to test for two common vulnerabilities – DROWN and ROBOT (which is an extension of the well known Bleichenbacher attack). Recently, Hanno Böck, Juraj Somorovsky, and Craig Young, responsible for discovery of the ROBOT vulnerability, have identified that tlsfuzzer was one of only two tools able to detect the vulnerability at the time they discovered it.

Det er etterfølgeren til Red Hat Linux. Red Hat Enterprise Linux (RHEL) er et kommersielt operativsystem og en Linuxdistribusjon som blir utviklet av Red Hat. All offisiell support og opplæring, sammen med Red Hat Certification Program, fokuserer på denne distribusjonen. Benevnelsene er et kommersielt .

The first automated upgrade path is from Red Hat Enterprise Linux OpenStack Platform 7 to Red Hat OpenStack Platform 8. Including all releases before Red Hat Enterprise Linux OpenStack Platform 7. In that case the upgrade would have to be performed version by version (7 to 8 to 9). In the case of one year releases, the upgrade needs to be performed within one year of the release date of the earlier Red Hat OpenStack Platform version. For example, the process would support upgrading from Red Hat OpenStack Platform 7 to Red Hat OpenStack Platform 8, but not upgrading from Red Hat OpenStack Platform 7 to Red Hat OpenStack Platform 9.

So things like IoT devices that are Bluetooth enabled along with a vulnerable kernel compiled without Stack Protection will be most at risk from this flaw. Well, the problem is going to be all those kernels that have been built without Stack Protection turned on. So if most distributions build kernels with Stack Protection, and Stack Protection has been available for many years before the flaw was introduced, where is the risk.
