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

- Ubuntu 12.04 LTS

Summary:

Apport could be made to expose privileged information.

Software Description:

dump files generated by setuid binaries. A local attacker could possibly
use this issue to obtain privileged information.

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

Ubuntu 13.10:
  apport                          2.12.5-0ubuntu2.1
