FreeBSD Security Advisory FreeBSD-SA-03:19.bind – A programming error in BIND 8 named can allow an attacker the ability to 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. Affected versions are up to FreeBSD 4.9-RELEASE and 5.1-RELEASE.
