Synopsis

The remote Red Hat host is missing one or more security updates.

Description

Updated kernel packages that fix one security issue are now available for Red Hat Enterprise Linux 6.5 Extended Update Support.

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.
