A new CUPS vulnerability update is available for Ubuntu Linux. Here the announcement:

Ubuntu Security Notice USN-185-1 September 20, 2005
cupsys vulnerability
CAN-2004-2154
===========================================================

A security issue affects the following Ubuntu releases:

Ubuntu 4.10 (Warty Warthog)

The following packages are affected:

cupsys

The problem can be corrected by upgrading the affected package to
version 1.1.20final+cvs20040330-4ubuntu16.5. In general, a standard
system upgrade is sufficient to effect the necessary changes.

Details follow:

A flaw was detected in the printer access control list checking in the
CUPS server. Printer names were compared in a case sensitive manner;
by modifying the capitalization of printer names, a remote attacker
could circumvent ACLs and print to printers he should not have access
to.

The Ubuntu 5.04 version of cupsys is not vulnerable against this.
