Synopsis :

The remote Red Hat host is missing one or more security updates.

Description :

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.

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.
