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.
