A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 13.10
- Ubuntu 13.04

- Ubuntu 12.04 LTS
Apport could be made to expose privileged information.
- apport - automatically generate crash reports for debugging
Martin Carpenter discovered that Apport set incorrect permissions on core
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 version:
- Ubuntu 13.10:
- apport 2.12.5-0ubuntu2.1
- Ubuntu 13.04:
- apport 2.9.2-0ubuntu8.5

- apport 2.0.1-0ubuntu17.6
