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
