tiff vulnerability

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

The TIFF library could be made to run programs as your login if it opened a specially crafted file.

Software description

  • tiff - TIFF manipulation and conversion tools


It was discovered that the TIFF library incorrectly handled certain JPEG
data. 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.
