|Description||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.|

the attack works with a certain non-negligible probability, but even
when successful, it only causes a TCP disconnect, which will (in most
circumstances) be reestablished right away, causing essentially no impact
