Ubuntu Security Notice 5841-1 - It was discovered that LibTIFF incorrectly handled certain malformed images. If a user or automated system were tricked into opening a specially crafted image, a remote attacker could crash the application, leading to a denial of service, or possibly execute arbitrary code with user privileges. This issue was only fixed in Ubuntu 14.04 ESM. It was discovered that LibTIFF was incorrectly accessing a data structure when processing data with the tiffcrop tool, which could lead to a heap buffer overflow. An attacker could possibly use this issue to cause a denial of service or execute arbitrary code.
