A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 12.04 LTS
- Ubuntu 11.10
- Ubuntu 11.04
- Ubuntu 10.04 LTS
Bind could be made to crash if it received specially crafted network traffic.

Einar Lonn discovered that Bind incorrectly initialized the failing-query
cache. A remote attacker could use this flaw to cause Bind to crash,
resulting in a denial of service.
The problem can be corrected by updating your system to the following package version:
