Ubuntu Security Notice 1416-1 - Alexander Gavrun discovered that the TIFF library incorrectly allocated space for a tile. If a user or automated system were tricked into opening a specially crafted TIFF image, a remote attacker could execute arbitrary code with user privileges, or crash the application, leading to a denial of service. It was discovered that the tiffdump utility incorrectly handled directory data structures with many directory entries. If a user or automated system were tricked into opening a specially crafted TIFF image, a remote attacker could crash the application, leading to a denial of service, or possibly execute arbitrary code with user privileges. This issue only applied to Ubuntu 8.04 LTS, Ubuntu 10.04 LTS, Ubuntu 10.10 and Ubuntu 11.04. Various other issues were also addressed.
