USN-1668-1: Apport update

17 December 2012

apport update

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

  • Ubuntu 12.04 LTS
  • Ubuntu 11.10
  • Ubuntu 10.04 LTS

Summary

A hardening measure was added to apport.

Software Description

  • apport - automatically generate crash reports for debugging

Details

Dan Rosenberg discovered that an application running under an AppArmor profile that allowed unconfined execution of apport-bug could escape confinement by calling apport-bug with a crafted environment. While not a vulnerability in apport itself, this update mitigates the issue by sanitizing certain variables in the apport-bug shell script.

Update instructions

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

Ubuntu 12.04 LTS
apport - 2.0.1-0ubuntu15.1
Ubuntu 11.10
apport - 1.23-0ubuntu4.1
Ubuntu 10.04 LTS
apport - 1.13.3-0ubuntu2.2

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.
