1. Summary:

Updated kernel packages that fix multiple security issues, address several
hundred bugs, and add numerous enhancements are now available as part of
the ongoing support and maintenance of Red Hat Enterprise Linux version 5.
This is the sixth regular update.

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 (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:

* A NULL pointer dereference flaw was found in the igb driver in the Linux
kernel. If both the Single Root I/O Virtualization (SR-IOV) feature and
promiscuous mode were enabled on an interface using igb, it could result in
a denial of service when a tagged VLAN packet is received on that
interface. (CVE-2010-4263, Important)

* A missing sanity check was found in vbd_create() in the Xen hypervisor
implementation. As CD-ROM drives are not supported by the blkback back-end
driver, attempting to use a virtual CD-ROM drive with blkback could trigger
a denial of service (crash) on the host system running the Xen hypervisor.
(CVE-2010-4238, Moderate)

* A flaw was found in the Linux kernel execve() system call implementation.
A local, unprivileged user could cause large amounts of memory to be
allocated but not visible to the OOM (Out of Memory) killer, triggering a
denial of service. (CVE-2010-4243, Moderate)

* A flaw was found in fixup_page_fault() in the Xen hypervisor
implementation. If a 64-bit para-virtualized guest accessed a certain area
of memory, it could cause a denial of service on the host system running
the Xen hypervisor. (CVE-2010-4255, Moderate)

* A missing initialization flaw was found in the bfa driver used by Brocade
Fibre Channel Host Bus Adapters. A local, unprivileged user could use this
flaw to cause a denial of service by reading a file in the
"/sys/class/fc_host/host#/statistics/" directory. (CVE-2010-4343, Moderate)

* Missing initialization flaws in the Linux kernel could lead to
information leaks. (CVE-2010-3296, CVE-2010-3877, CVE-2010-4072,
CVE-2010-4073, CVE-2010-4075, CVE-2010-4080, CVE-2010-4081, CVE-2010-4158,

Red Hat would like to thank Kosuke Tatsukawa for reporting CVE-2010-4263;
Vladymyr Denysov for reporting CVE-2010-4238; Brad Spengler for reporting
CVE-2010-4243; Dan Rosenberg for reporting CVE-2010-3296, CVE-2010-4073,
CVE-2010-4075, CVE-2010-4080, CVE-2010-4081, and CVE-2010-4158; Vasiliy
Kulikov for reporting CVE-2010-3877; and Kees Cook for reporting

These updated packages also include several hundred bug fixes for and
enhancements to the Linux kernel. Space precludes documenting each of these
changes in this advisory and users are directed to the Red Hat Enterprise
Linux 5.6 Release Notes for information on the most significant of these


Refer to the kernel chapter in the Red Hat Enterprise Linux 5.6 Technical
Notes for further information:


All Red Hat Enterprise Linux 5 users are advised to install these updated
packages, which address these vulnerabilities as well as fixing the bugs
and adding the enhancements noted in the Red Hat Enterprise Linux 5.6
Release Notes and Technical Notes. 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

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.
