Detail

Problem Description:

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
