"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.

The Common UNIX(r) 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."
