Detail

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

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