CVE-2002-2211

BIND 4 and BIND 8, when resolving recursive DNS queries for arbitrary hosts, allows remote attackers to conduct DNS cache poisoning via a birthday attack that uses a large number of open queries for the same resource record (RR) combined with spoofed responses, which increases the possibility of successfully spoofing a response in a way that is more efficient than brute force methods.
