(RHSA-2005:571) cups security update

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

When processing a request, the CUPS scheduler would use case-sensitive
matching on the queue name to decide which authorization policy should be
used. However, queue names are not case-sensitive. An unauthorized user
could print to a password-protected queue without needing a password. The
Common Vulnerabilities and Exposures project has assigned the name
CAN-2005-2154 to this issue.

Please note that the version of CUPS included in Red Hat Enterprise Linux 4
is not vulnerable to this issue.

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