    Hello,

    You can update packages provided by your OS with the following command:

    Code:
    yum update
    Could you elaborate more on the specific security risk you are referring to, and let us know which OS is installed?

    Thanks!

    Hello,

    Could you elaborate on the specific security concern this is in reference to? That's the most recent version published by CentOS for CentOS 7.

    Thank you.

    Hello,

    The system is already using the most recent version published for that package by CentOS. You should not update the package manually. Could you elaborate on the specific security concern this is in reference to?

    Thanks!

    I ran into a similar issue with an (apparently) old version of a file on CentOS, but I found out that version numbers alone aren't an accurate representation of security vulnerabilities in CentOS because they backport security fixes, retaining old version numbers.
    You can read more about it here:
