Medium: kernel

Issue Overview:

A flaw was found in the way the Linux kernel’s XFS file system handled replacing of remote attributes under certain conditions. A local user with access to XFS file system mount could potentially use this flaw to escalate their privileges on the system.

Affected Packages:

kernel

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