bind8 negative cache poison attack

Description:

A programming error in BIND 8 named can result in a DNS message being incorrectly cached as a negative response. As a result, an attacker may arrange for malicious DNS messages to be delivered to a target name server, and cause that name server to cache a negative response for some target domain name. The name server would thereafter respond negatively to legitimate queries for that domain name, resulting in a denial-of-service for applications that require DNS.
