The problem can be corrected by upgrading your system to the following package versions: Ubuntu 6.06 LTS: cupsys 1.2.2-0ubuntu0.6.06.15 Ubuntu 8.04 LTS: cupsys 1.3.7-1ubuntu3.6 Ubuntu 8.10: cups 1.3.9-2ubuntu9.3 Ubuntu 9.04: cups 1.3.9-17ubuntu3.4 Ubuntu 9.10: cups 1.4.1-5ubuntu2.1 In general, a standard system upgrade is sufficient to effect the necessary changes. Details follow: Aaron Sigel discovered that the CUPS web interface incorrectly protected against cross-site scripting (XSS) and cross-site request forgery (CSRF) attacks. If an authenticated user were tricked into visiting a malicious website while logged into CUPS, a remote attacker could modify the CUPS configuration and possibly steal confidential data.
