USN-1668-1: Apport update

Releases

• Ubuntu 12.04
• Ubuntu 11.10
• Ubuntu 10.04

Packages

• 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

• apport - 2.0.1-0ubuntu15.1

Ubuntu 11.10

• apport - 1.23-0ubuntu4.1

Ubuntu 10.04

• apport - 1.13.3-0ubuntu2.2

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