    Centos 3.x Kernel update.

    Hello,
    After receiving the following warning in WHM, I would like to ask some questions here:

    Security Notice:
    There are several known Linux kernel exploits which may allow local privilege escalation. These exploits have become commonplace in recent weeks and can be avoided by ensuring that your kernel is updated to the latest available version. While cPanel will help ensure your system services and software are up to date, kernel updates are outside the scope of cPanel. Kernels with known vulnerabilities include, but are not limited to, 2.6.9-22 and 2.6.9-34. Please check your running kernel for updates periodically. This will help ensure the overall integrity of your server and data.

    My Kernel is 2.4.21-40.ELsmp and I am running Centos 3.7.
    Which is the latest kernel version for me? (2.4.21-47.EL ?).
    Is there a serious reason for switching to Centos 4?
    How long does it take for updating kernel and how long for updating to Centos 4 (for a professional to perform these tasks)?

    Thank you,
    Rocco.

    Kernel = under 30 mins. Migration to centos 4 - 1 hour to 3 hours.


    2.4.21-47.EL is the latest for you unless you want to compile.

    Those security messages were for centos 4/rhel4 not for your operating system

    Are you sure that my OS is secure?
    Is there a necessity switching to centos 4?

    rhel3/centos3 will be supported for a few years no need to update.

    not on cpanel, they add it to the skip list you need to use the -f flag.

    You mean force update? But most probably it worked with me on my last server with Dediwebhost. Although its not a problem just to add -f to force the update
