(RHSA-2005:772) cups security update

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

A bug was found in the way CUPS processes malformed HTTP requests. It is
possible for a remote user capable of connecting to the CUPS daemon to
issue a malformed HTTP GET request that causes CUPS to enter an
infinite loop. The Common Vulnerabilities and Exposures project
(cve.mitre.org) has assigned the name CAN-2005-2874 to this issue.

Two small bugs have also been fixed in this update. A signal handling
problem has been fixed that could occasionally cause the scheduler to stop
when told to reload. A problem with tracking open file descriptors under
certain specific circumstances has also been fixed.

All users of CUPS should upgrade to these erratum packages, which contain a
patch to correct this issue.
