"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.

Note that Tenable Network Security has extracted the preceding
description block directly from the Ubuntu security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."
