3. Description:
The Common UNIX� 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.
4. Solution:
Before applying this update, make sure that all previously-released errata
