Details

Pedro Ribeiro discovered that LibTIFF incorrectly handled certain
malformed images when using the gif2tiff tool. If a user or automated
system were tricked into opening a specially crafted GIF 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
affected Ubuntu 10.04 LTS, Ubunu 12.04 LTS, Ubuntu 12.10 and Ubuntu 13.10.
