=====================================================================

 

1. Summary:

 

Updated kernel packages that fix multiple security issues and various bugs

are now available for Red Hat Enterprise Linux 5.

 

The Red Hat Security Response Team has rated this update as having low

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 (v. 5 server) - i386, ia64, noarch, ppc, s390x, x86_64

Red Hat Enterprise Linux Desktop (v. 5 client) - i386, noarch, x86_64

 

3. Description:

 

The kernel packages contain the Linux kernel, the core of any Linux

operating system.

 

This update fixes the following security issues:

 

* Information leaks in the Linux kernel could allow a local, unprivileged

user to leak kernel memory to user-space. (CVE-2012-6544, CVE-2012-6545,

CVE-2013-3222, CVE-2013-3224, CVE-2013-3231, CVE-2013-3235, Low)

 

* An information leak was found in the Linux kernel's POSIX signals

implementation. A local, unprivileged user could use this flaw to bypass

the Address Space Layout Randomization (ASLR) security feature.

(CVE-2013-0914, Low)

 

* A heap-based buffer overflow in the way the tg3 Ethernet driver parsed

the vital product data (VPD) of devices could allow an attacker with

physical access to a system to cause a denial of service or, potentially,

escalate their privileges. (CVE-2013-1929, Low)

 

This update also fixes the following bugs:

 

* Previously on system boot, devices with associated Reserved Memory Region

Reporting (RMRR) information had lost their RMRR information after they

were removed from the static identity (SI) domain. Consequently, a system

unexpectedly terminated in an endless loop due to unexpected NMIs triggered

by DMA errors. This problem was observed on HP ProLiant Generation 7 (G7)

and 8 (Gen8) systems. This update prevents non-USB devices that have RMRR

information associated with them from being placed into the SI domain

during system boot. HP ProLiant G7 and Gen8 systems that contain devices

with the RMRR information now boot as expected. (BZ#957606)

 

* Previously, the kernel's futex wait code used timeouts that had

granularity in milliseconds. Also, when passing these timeouts to system

calls, the kernel converted the timeouts to "jiffies". Consequently,

programs could time out inaccurately which could lead to significant

latency problems in certain environments. This update modifies the futex

wait code to use a high-resolution timer (hrtimer) so the timeout

granularity is now in microseconds. Timeouts are no longer converted to

"jiffies" when passed to system calls. Timeouts passed to programs are now

accurate and the programs time out as expected. (BZ#958021)

 

* A recent change modified the size of the task_struct structure in the

floating point unit (fpu) counter. However, on Intel Itanium systems, this

change caused the kernel Application Binary Interface (kABI) to stop

working properly when a previously compiled module was loaded, resulting in

a kernel panic. With this update the change causing this bug has been

reverted so the bug can no longer occur. (BZ#966878)

 

* The cxgb4 driver previously did not clear data structures used for

firmware requests. Consequently, when initializing some Chelsio's

Terminator 4 (T4) adapters, a probe request could fail because the request

was incompatible with the adapter's firmware. This update modifies the

cxgb4 driver to properly initialize firmware request structures before

sending a request to the firmware and the problem no longer occurs.

(BZ#971872)

 

Users should 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.
