Descriptions

TCP, when using a large Window Size, makes it easier for remote attackers to guess sequence numbers and cause a denial of service (connection loss) to persistent TCP connections by repeatedly injecting a TCP RST packet, especially in protocols that use long-lived connections, such as BGP.

TCP, cuando se usa un tamaño de ventana de transmisión grande, hace más fácil a atacantes remotos adivinar números de secuencia y causar una denegación de servicio (pérdida de la conexión) en conexiones TCP persistentes inyectando repetidamente un paquete TCP RST, especialmente en protocolos que usan conexiones de vida larga, como BGP.
