Description

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

This update has been rated as having moderate 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.

A NULL pointer dereference flaw was found in the way CUPS handled subscriptions for printing job completion notifications. A local user could use this flaw to crash the CUPS daemon by submitting a large number of printing jobs requiring mail notification on completion, leading to a denial of service. (CVE-2008-5183)

Users of cups should upgrade to these updated packages, which contain a backported patch to correct this issue.
