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.
