Medium: kernel

Issue Overview:

The ExecShield feature does not properly handle use of many shared libraries by a 32-bit executable file, which makes it easier for context-dependent attackers to bypass the ASLR protection mechanism by leveraging a predictable base address for one of these libraries.

Affected Packages:

kernel

Issue Correction:
Run yum update kernel to update your system. You will need to reboot your system in order for the new kernel to be running.
