Synopsis :

The remote Scientific Linux host is missing one or more security
updates.

Description :

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.
