Advisory ID: RHSA-2009:1082-01
Product: Red Hat Enterprise Linux
Advisory URL: https://rhn.redhat.com/errata/RHSA-2009-1082.html
Issue date: 2009-06-03
CVE Names: CVE-2009-0949
=====================================================================

1. Summary:

Updated cups packages that fix one security issue are now available for Red
Hat Enterprise Linux 5.

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

2. Relevant releases/architectures:

Red Hat Enterprise Linux Desktop (v. 5 client) - i386, x86_64
RHEL Desktop Workstation (v. 5 client) - i386, x86_64

3. Description:

The Common UNIX® Printing System (CUPS) provides a portable printing layer
for UNIX operating systems. The Internet Printing Protocol (IPP) allows
users to print and manage printing-related tasks over a network.

A NULL pointer dereference flaw was found in the CUPS IPP routine, used for
processing incoming IPP requests for the CUPS scheduler. An attacker could
use this flaw to send specially-crafted IPP requests that would crash the
cupsd daemon. (CVE-2009-0949)

Red Hat would like to thank Anibal Sacco from Core Security Technologies
for reporting this issue.

Users of cups are advised to upgrade to these updated packages, which
contain a backported patch to correct this issue. After installing this
update, the cupsd daemon will be restarted automatically.

4. Solution:

Before applying this update, make sure that all previously-released
