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