=========================================================== Ubuntu Security Notice USN-760-1 April 16, 2009 cups, cupsys vulnerability CVE-2009-0163 =========================================================== A security issue affects the following Ubuntu releases: Ubuntu 6.06 LTS Ubuntu 7.10 Ubuntu 8.04 LTS Ubuntu 8.10 This advisory also applies to the corresponding versions of Kubuntu, Edubuntu, and Xubuntu. The problem can be corrected by upgrading your system to the following package versions: Ubuntu 6.06 LTS: libcupsimage2 1.2.2-0ubuntu0.6.06.13 Ubuntu 7.10: libcupsimage2 1.3.2-1ubuntu7.10 Ubuntu 8.04 LTS: libcupsimage2 1.3.7-1ubuntu3.4 Ubuntu 8.10: libcupsimage2 1.3.9-2ubuntu9.1 In general, a standard system upgrade is sufficient to effect the necessary changes. Details follow: It was discovered that CUPS did not properly check the height of TIFF images. If a user or automated system were tricked into opening a crafted TIFF image file, a remote attacker could cause a denial of service or possibly execute arbitrary code with user privileges. In Ubuntu 7.10, 8.04 LTS, and 8.10, attackers would be isolated by the AppArmor CUPS profile.
