==========================================================================

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

- Ubuntu 13.04
- Ubuntu 12.10
- Ubuntu 12.04 LTS
- Ubuntu 10.04 LTS

Summary:

Bind could be made to crash if it received specially crafted network
traffic.

Software Description:

Details:

Maxim Shudrak discovered that Bind incorrectly handled certain malformed
rdata. A remote attacker could use this flaw with a specially crafted
query to cause Bind to stop responding, resulting in a denial of service.

The problem can be corrected by updating your system to the following
package versions:
