Important: kernel security update

Advisory:	RHSA-2009:1541-1
Type:	Security Advisory
Severity:	Important
Issued on:	2009-11-03
Last updated on:	2009-11-03
Affected Products:	Red Hat Desktop (v. 4) Red Hat Enterprise Linux AS (v. 4) Red Hat Enterprise Linux AS (v. 4.8.z) Red Hat Enterprise Linux ES (v. 4) Red Hat Enterprise Linux ES (v. 4.8.z) Red Hat Enterprise Linux WS (v. 4)
OVAL:	com.redhat.rhsa-20091541.xml
CVEs (cve.mitre.org):	CVE-2009-3547

Details

Updated kernel packages that fix security issues are now available for Red
Hat Enterprise Linux 4.

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

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

This update fixes the following security issues:

* a NULL pointer dereference flaw was found in each of the following
functions in the Linux kernel: pipe_read_open(), pipe_write_open(), and
pipe_rdwr_open(). When the mutex lock is not held, the i_pipe pointer could
be released by other processes before it is used to update the pipe's
reader and writer counters. This could lead to a local denial of service or
privilege escalation. (CVE-2009-3547, Important)

Users should upgrade to these updated packages, which contain a backported
patch 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
http://kbase.redhat.com/faq/docs/DOC-11259
