tiff vulnerabilities

A security issue affects these releases of Ubuntu and its derivatives:

  • Ubuntu 13.04
  • Ubuntu 12.10
  • Ubuntu 12.04 LTS
  • Ubuntu 10.04 LTS


LibTIFF could be made to crash or run programs as your login if it opened a specially crafted file.

Software Description

  • tiff - Tag Image File Format (TIFF) library


Emmanuel Bouillon discovered that LibTIFF incorrectly handled certain malformed images when using the tiff2pdf tool. 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.
