A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 14.10

USN-2569-1 fixed a vulnerability in Apport. Tavis Ormandy discovered that the fixed packages were still vulnerable to a privilege escalation attack. This update completely disables crash report handling for containers until a more complete solution is available.
Original advisory details:
Stéphane Graber and Tavis Ormandy independently discovered that Apport incorrectly handled the crash reporting feature. A local attacker could use this issue to gain elevated privileges.
The problem can be corrected by updating your system to the following package versions:
