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

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

Summary:

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

Software Description:
- bind9: Internet Domain Name Server

Details:

Jayachandran Palanisamy discovered that the Bind resolver incorrectly
handled fetch cleanup sequencing. A remote attacker could possibly use this
issue to cause Bind to crash, resulting in a denial of service.
