Updated CUPS packages that fix a security issue are now available for Red
Hat Enterprise Linux 3.
This update has been rated as having moderate security impact by the CentOS
Security Response Team.
The Common UNIX Printing System (CUPS) provides a portable printing layer for
UNIX(R) 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 CentOS 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.
