RHSA-2010:0342 - Important: kernel security and bug fix update

Synopsis

Important: kernel security and bug fix update

Type/Severity

Security Advisory Important

Topic

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.

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.

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 This content is not included.http://kbase.redhat.com/faq/docs/DOC-11259
