Netregistry’s expert security team will optimise your environment and make a series of modifications to your operating system and control panel installation to enhance the reliability of your server. Server hardening is designed to save you time and resources.
If this is the case it is recommended to use some other alternative approach on how to check CentOS version on your system.

How do I upgrade my exim mail server. I'm using Cpanel CentOS Linux server. How do I update to the latest version of exim under cPanel .
Like one needs to check if a folder is writable before. Checking what PHP version I’m running. I’m running Centos 5 and I need to know what version of PHP I’m.
The security vulnerablity lies within the SSLv3 protocol itself, so anything that uses SSLv3 can be affected. Please check your facts. This is why email providers are disabling SSLv3 support for their own services. Because SMTP does in fact accept SSLv3 connections, it is relevant.
The good news is that much of the complexity is there to allow experienced email administrators to achieve complicated configurations for large scale enterprise installations. The fact is that for most Linux users it is relatively straight forward to set up a basic email system so that they can send and receive electronic mail.
Cpanels latest update might fix this: WHM>> Service Configuration>> Exim Configuration Manger>> Advanced Editor>> openssl_options = +no_sslv2 +no_sslv3. EXIM

tls_require_ciphers = ALL:-SSLv3:. ADH:RC4+RSA:+HIGH:+MEDIUM:-LOW:-SSLv2:-EXP

Just about every website that discusses this in detail concedes. The SSLv3 protocol is no longer secure. I’m sorry, but you are incorrect. You are completely misinterpreting the whitepaper. Again, the PoC is only siting HTTP cookies as an non-exclusive example.
