"Updated CUPS packages that fix a security issue are now available for
Red Hat Enterprise Linux 3, 4, and 5.

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

The Common UNIX Printing System (CUPS) provides a portable printing
layer for UNIX(R) operating systems.

A bug was found in the way CUPS handled SSL negotiation. A remote user
capable of connecting to the CUPS daemon could cause a denial of
service to other CUPS users. (CVE-2007-0720)

All users of CUPS should upgrade to these updated packages, which
contain a backported patch introducing a timeout, which prevents
connections being kept open for an arbitrarily long time."
