This script is Copyright (C) 2012 Tenable Network Security, Inc.


Synopsis :

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

Description :

This update fixes the following security issues :

- A buffer overflow flaw was found in the
load_mixer_volumes() function in the Linux kernel's Open
Sound System (OSS) sound driver. On 64-bit PowerPC
systems, a local, unprivileged user could use this flaw
to cause a denial of service or escalate their
privileges. (CVE-2010-4527, Important)

- A missing boundary check was found in the dvb_ca_ioctl()
function in the Linux kernel's av7110 module. On systems
that use old DVB cards that require the av7110 module, a
local, unprivileged user could use this flaw to cause a
denial of service or escalate their privileges.
(CVE-2011-0521, Important)

- A missing initialization flaw was found in the
ethtool_get_regs() function in the Linux kernel's
ethtool IOCTL handler. A local user who has the
CAP_NET_ADMIN capability could use this flaw to cause an
information leak. (CVE-2010-4655, Low)

These updated kernel packages also fix hundreds of bugs and add
numerous enhancements.

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