USN-2744-1: Apport vulnerability
Ubuntu Security Notice USN-2744-1
24th September, 2015
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 15.04
- Ubuntu 14.04 LTS
- Ubuntu 12.04 LTS
Apport could be made to crash or overwrite files as an administrator.
- apport - automatically generate crash reports for debugging
Halfdog discovered that Apport incorrectly handled kernel crash dump files.
A local attacker could use this issue to cause a denial of service, or
possibly elevate privileges. The default symlink protections for affected
releases should reduce the vulnerability to a denial of service.
The problem can be corrected by updating your system to the following package version:
- Ubuntu 15.04:
- apport 2.17.2-0ubuntu1.5
- Ubuntu 14.04 LTS:
- apport 2.14.1-0ubuntu3.15
- Ubuntu 12.04 LTS:
- apport 2.0.1-0ubuntu17.10
To update your system, please follow these instructions: https://wiki.ubuntu.com/Security/Upgrades.
In general, a standard system update will make all the necessary changes.
