One of the easiest ways to check susceptibility is to check the glibc version that is used.
We will see how to check vulnerability in Ubuntu, Debian, Cent OS, and RHEL.
Let’s see how to check if your system is vulnerable and steps to protect it.
Once you know what is glibc bug and how it can affect your devices you can start working on patch the vulenarability.
This check has since been relaxed to 2.17 (the version in Red Hat Enterprise Linux 7), but it is still worth discussing what we can do to support application binaries in Red Hat Enterprise Linux which require a newer glibc version to run.
