...

DEBIAN-CVE-2004-0230

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...
