==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
– Ubuntu 15.10

Summary:
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
Details:
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.
