===========================================================================

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

- Ubuntu 16.10
- Ubuntu 16.04 LTS
- Ubuntu 14.04 LTS
- Ubuntu 12.04 LTS

Summary:

libXpm could be made to crash or run programs if it opened a specially
crafted file.

Software Description:
- libxpm: X11 pixmap library

Details:

It was discovered that libXpm incorrectly handled certain XPM files. If a
user or automated system were tricked into opening a specially crafted XPM
file, a remote attacker could use this issue to cause libXpm to crash,
resulting in a denial of service, or possibly execute arbitrary code.
