==========================================================================
Ubuntu Security Notice USN-3185-1
February 01, 2017

libxpm vulnerability
==========================================================================

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.

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 16.10:
  libxpm4                         1:3.5.11-1ubuntu0.16.10.1

Ubuntu 16.04 LTS:
  libxpm4                         1:3.5.11-1ubuntu0.16.04.1

Ubuntu 14.04 LTS:
  libxpm4                         1:3.5.10-1ubuntu0.1

Ubuntu 12.04 LTS:
  libxpm4                         1:3.5.9-4ubuntu0.1

After a standard system update you need to restart your session to make
all the necessary changes.
