=====================================================================
                   Red Hat Security Advisory

Synopsis:          Important: kernel security and bug fix update
Advisory ID:       RHSA-2014:0476-01
Product:           Red Hat Enterprise Linux
Advisory URL:      https://rhn.redhat.com/errata/RHSA-2014-0476.html
Issue date:        2014-05-07
CVE Names:         CVE-2013-6381 CVE-2013-6383 
=====================================================================

1. Summary:

Updated kernel packages that fix two security issues and one bug are now
available for Red Hat Enterprise Linux 5.9 Extended Update Support.

The Red Hat Security Response Team has rated this update as having
Important security impact. Common Vulnerability Scoring System (CVSS) base
scores, which give detailed severity ratings, are available for each
vulnerability from the CVE links in the References section.

2. Relevant releases/architectures:

Red Hat Enterprise Linux EUS (v. 5.9 server) - i386, ia64, noarch, ppc, s390x, x86_64

3. Description:

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

* A buffer overflow flaw was found in the way the qeth_snmp_command()
function in the Linux kernel's QETH network device driver implementation
handled SNMP IOCTL requests with an out-of-bounds length. A local,
unprivileged user could use this flaw to crash the system or, potentially,
escalate their privileges on the system. (CVE-2013-6381, Important)

* A flaw was found in the way the Linux kernel's Adaptec RAID controller
(aacraid) checked permissions of compat IOCTLs. A local attacker could use
this flaw to bypass intended security restrictions. (CVE-2013-6383,
Moderate)

This update also fixes the following bug:

* Running a process in the background on a GFS2 file system could sometimes
trigger a glock recursion error that resulted in a kernel panic. This
happened when a readpage operation attempted to take a glock that had
already been held by another function. To prevent this error, GFS2 now
verifies whether the glock is already held when performing the readpage
operation. (BZ#1077789)

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

4. Solution:

Before applying this update, make sure all previously-released errata
relevant to your system have been applied.

This update is available via the Red Hat Network. Details on how to
use the Red Hat Network to apply this update are available at
https://access.redhat.com/knowledge/articles/11258

To install kernel packages manually, use "rpm -ivh [package]". Do not
use "rpm -Uvh" as that will remove the running kernel binaries from
your system. You may use "rpm -e" to remove old kernels after
determining that the new kernel functions properly on your system.

5. Bugs fixed (https://bugzilla.redhat.com/):

1033530 - CVE-2013-6383 Kernel: AACRAID Driver compat IOCTL missing capability check
1033600 - CVE-2013-6381 Kernel: qeth: buffer overflow in snmp ioctl
