Technical Cyber Security Alert TA04-111A – Most implementations of the Border Gateway Protocol (BGP) rely on the Transmission Control Protocol (TCP) to maintain persistent unauthenticated network sessions. There is a vulnerability in TCP which allows remote attackers to terminate network sessions. Sustained exploitation of this vulnerability could lead to a denial of service condition; in the case of BGP systems, portions of the Internet community may be affected. Routing operations would recover quickly after such attacks ended.
