USN-985-1: mountall vulnerability
8 September 2010
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 10.04 LTS
Local root escalation via writable udev rules.

The problem can be corrected by updating your system to the following package versions:
To update your system, please follow these instructions: https://wiki.ubuntu.com/Security/Upgrades.
