apport update

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

- Ubuntu 12.04 LTS
- Ubuntu 11.10
- Ubuntu 10.04 LTS


A hardening measure was added to apport.

Software Description:
- apport: automatically generate crash reports for debugging


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.
