Red Hat Security Advisory

Synopsis: Important: kernel security update
Advisory ID: RHSA-2010:0019-01
Product: Red Hat Enterprise Linux
Advisory URL: https://rhn.redhat.com/errata/RHSA-2010-0019.html
Issue date: 2010-01-07
CVE Names: CVE-2007-4567 CVE-2009-4536 CVE-2009-4537
CVE-2009-4538
=====================================================================

1. Summary:

Updated kernel packages that fix multiple security issues are now available
for Red Hat Enterprise Linux 5.

This update has been rated as having important security impact by the Red
Hat Security Response Team.

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 flaw was found in the IPv6 Extension Header (EH) handling
implementation in the Linux kernel. The skb-gt;dst data structure was not
properly validated in the ipv6_hop_jumbo() function. This could possibly
lead to a remote denial of service. (CVE-2007-4567, Important)

* a flaw was found in each of the following Intel PRO/1000 Linux drivers in
the Linux kernel: e1000 and e1000e. A remote attacker using packets larger
than the MTU could bypass the existing fragment check, resulting in
partial, invalid frames being passed to the network stack. These flaws
could also possibly be used to trigger a remote denial of service.
(CVE-2009-4536, CVE-2009-4538, Important)

* a flaw was found in the Realtek r8169 Ethernet driver in the Linux
kernel. Receiving overly-long frames with network cards supported by this
driver could possibly result in a remote denial of service. (CVE-2009-4537,
Important)

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 that all previously-released
errata relevant to your system have been applied.

This update is available via Red Hat Network. Details on how to use
