Ubuntu Security Notice USN-2007-1
24th October, 2013
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 13.10
- Ubuntu 13.04
- Ubuntu 12.10
- 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
- Ubuntu 12.10:
- apport 2.6.1-0ubuntu13
- Ubuntu 12.04 LTS:
- apport 2.0.1-0ubuntu17.6
To update your system, please follow these instructions: https://wiki.ubuntu.com/Security/Upgrades.
In general, a standard system update will make all the necessary changes.
