Synopsis:          Important: kernel security update
Advisory ID:       SLSA-2013:0830-1
Issue Date:        2013-05-16
CVE Numbers:       CVE-2013-2094
--

This update fixes the following security issue:

* It was found that the Scientific Linux 6.1 kernel update
(SLSA-2011:0542) introduced an integer conversion issue in the Linux
kernel's Performance Events implementation. This led to a user-supplied
index into the perf_swevent_enabled array not being validated properly,
resulting in out-of-bounds kernel memory access. A local, unprivileged
user could use this flaw to escalate their privileges. (CVE-2013-2094,
Important)

A public exploit that affects Scientific Linux 6 is available.

Refer to Red Hat Knowledge Solution 373743 for further information
and mitigation instructions for users who are unable to immediately
apply this update.

The system must be rebooted for this update to take effect.
