Updated kernel packages that fix one security issue are now available for
Red Hat Enterprise Linux 5.

Red Hat Product Security has rated this update as having Important security
impact. A Common Vulnerability Scoring System (CVSS) base score, which
gives a detailed severity rating, is available from the CVE link in the
References section.

The kernel packages contain the Linux kernel, the core of any Linux
operating system.

* A flaw was found in the way the Linux kernel handled GS segment register
base switching when recovering from a #SS (stack segment) fault on an
erroneous return to user space. A local, unprivileged user could use this
flaw to escalate their privileges on the system. (CVE-2014-9322, Important)

Red Hat would like to thank Andy Lutomirski for reporting this issue.

All kernel users are advised to upgrade to these updated packages, which
contain a backported patch to correct this issue. The system must be
rebooted for this update to take effect.
