- 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
Ubuntu 11.10
Ubuntu 10.04
In general, a standard system update will make all the necessary changes.
