FreeBSD Security Advisory FreeBSD-SA-02:36 - A denial of service vulnerability has been discovered in FreeBSD NFS. A part of the NFS server code charged with handling incoming RPC messages had an error which, when the server received a message with a zero-length payload, would cause it to reference the payload from the previous message, creating a loop in the message chain. This would later cause an infinite loop in a different part of the NFS server code which tried to traverse the chain.
