pidgin vulnerabilities
============================================================================

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

- Ubuntu 15.10
- Ubuntu 14.04 LTS
- Ubuntu 12.04 LTS

Summary:

Pidgin could be made to crash or run programs if it received
specially crafted network traffic.

Software Description:
- pidgin: graphical multi-protocol instant messaging client for X

Details:

Yves Younan discovered that Pidgin contained multiple issues in the MXit
protocol support. A remote attacker could use this issue to cause Pidgin 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 15.10:
  libpurple0                      1:2.10.11-0ubuntu4.2

Ubuntu 14.04 LTS:
  libpurple0                      1:2.10.9-0ubuntu3.3

Ubuntu 12.04 LTS:
  libpurple0                      1:2.10.3-0ubuntu1.7

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