A security issue affects the following Ubuntu releases:
Ubuntu 4.10 (Warty Warthog)
The following packages are affected:
The problem can be corrected by upgrading the affected package to

system upgrade is sufficient to effect the necessary changes.
A flaw was detected in the printer access control list checking in the

by modifying the capitalization of printer names, a remote attacker
could circumvent ACLs and print to printers he should not have access
The Ubuntu 5.04 version of cupsys is not vulnerable against this.
