Medium: kernel

Issue Overview:

A flaw was found in the way seunshare, a utility for running executables under a different security context, used the capng_lock functionality of the libcap-ng library. The subsequent invocation of suid root binaries that relied on the fact that the setuid() system call, among others, also sets the saved set-user-ID when dropping the binaries’ process privileges, could allow a local, unprivileged user to potentially 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.
