The Ubuntu Security Note USN-1669-2 outlines actions taken to address a software vulnerability impacting various versions.
A hardening measure was added to apport.

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

In general, a standard system update will make all the necessary changes.
