RHSA-2009:1055 - 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 a bug are now available for Red Hat Enterprise Linux 5.2 Extended Update Support.

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

Description

The kernel packages contain the Linux kernel, the core of any Linux operating system.

This update fixes the following security issue:

  • a buffer overflow was found in the Linux kernel Partial Reliable Stream Control Transmission Protocol (PR-SCTP) implementation. This could, potentially, lead to a remote denial of service or arbitrary code execution if a Forward-TSN chunk is received with a large stream ID. Note: An established connection between SCTP endpoints is necessary to exploit this vulnerability. Refer to the Knowledgebase article in the References section for further information. (CVE-2009-0065, Important)

This update also fixes the following bug:

  • a problem in the way the i5000_edac module reported errors may have caused the console on some systems to be flooded with errors, similar to the following:

EDAC i5000 MC0: NON-FATAL ERROR Found!!! 1st NON-FATAL Err Reg= [hex value] EDAC i5000: NON-Retry Errors, bits= [hex value]

After installing this update, the console will not be flooded with these errors. (BZ#494734)

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 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 the Red Hat Network to apply this update are available at This content is not included.http://kbase.redhat.com/faq/docs/DOC-11259
