Liebe Kolleginnen und Kollegen,

soeben erreichte uns nachfolgendes RedHat Security Advisory. Wir geben
diese Informationen unveraendert an Sie weiter.

CVE-2009-4538 - Schwachstelle im Linux e1000e Treiber

  Der Linux e1000e Treiber enthaelt eine Schwachstelle, die zu einem
  Systemabsturz fuehren kann, wenn Hardware Rx Size Filtering benutzt und
  Pakete empfangen werden, die groesser als die konfigurierte MTU sind.
  Entfernte Angreifer koennen diese Schwachstelle zu einem Denial of
  Service Angriff gegen das System ausnutzen. Die Schwachstelle ist
  analog zu CVE-2009-4537 fuer RTL8169.

CVE-2010-0008 - Schwachstelle in der SCTP-Implementation des
Linux-Kernels

  Durch einen Null-Pointer-Referenzierungsfehler in der
  SCTP-Implementation des Linux-Kernels kann ein entfernter Angreifer
  einen Denial-of-Service-Angriff durchfuehren, indem er ein
  manipuliertes SCTP-Paket an das betroffene System schickt.

Betroffen sind die folgenden Software Pakete und Plattformen:

  Die Kernel-Pakete

  Red Hat Enterprise Linux AS version 4.7.z - i386, ia64, noarch, ppc,
  s390, s390x, x86_64
  Red Hat Enterprise Linux ES version 4.7.z - i386, ia64, noarch, x86_64
  

Vom Hersteller werden ueberarbeitete Pakete zur Verfuegung gestellt.

                   Red Hat Security Advisory

Synopsis:          Important: kernel security and bug fix update
Advisory ID:       RHSA-2010:0342-01
Product:           Red Hat Enterprise Linux
Advisory URL:      https://rhn.redhat.com/errata/RHSA-2010-0342.html
Issue date:        2010-04-06
CVE Names:         CVE-2010-0008 
=====================================================================

1. Summary:

Updated kernel packages that fix one security issue and one bug are now
available for Red Hat Enterprise Linux 4.7 Extended Update Support.

The Red Hat Security Response Team has rated this update as having
important security impact. A Common Vulnerability Scoring System (CVSS)
base score, which gives a detailed severity rating, is available from the
CVE link in the References section.

2. Relevant releases/architectures:

Red Hat Enterprise Linux AS version 4.7.z - i386, ia64, noarch, ppc, s390, s390x, x86_64
Red Hat Enterprise Linux ES version 4.7.z - i386, ia64, 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 issue:

* a flaw was found in the sctp_rcv_ootb() function in the Linux kernel
Stream Control Transmission Protocol (SCTP) implementation. A remote
attacker could send a specially-crafted SCTP packet to a target system,
resulting in a denial of service. (CVE-2010-0008, Important)

This update also fixes the following bug:

* the fix for CVE-2009-4538 provided by RHSA-2010:0111 introduced a
regression, preventing Wake on LAN (WoL) working for network devices using
the Intel PRO/1000 Linux driver, e1000e. Attempting to configure WoL for
such devices resulted in the following error, even when configuring valid
options:

"Cannot set new wake-on-lan settings: Operation not supported not
setting wol"

This update resolves this regression, and WoL now works as expected for
network devices using the e1000e driver. (BZ#565495)

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
http://kbase.redhat.com/faq/docs/DOC-11259

5. Bugs fixed (http://bugzilla.redhat.com/):

555658 - CVE-2010-0008 kernel: sctp remote denial of service
565495 - e1000e: wol is broken in kernel 2.6.9-89.19 [rhel-4.7.z]
