This talk will divulge new technical details about Outpost24s (Jack C. Louis) research into TCP state table manipulation vulnerabilities that affect availability. Specifically this talk will showcase new attacks that will render a remote system unavailable using a very low bandwidth attack stream. Attacks against Windows, BSD, Linux, and embedded systems TCP/IP stack implementations will be discussed and demonstrated. In-line devices that keep track of state for multiple systems (read firewalls) tend to feel the effects of the attack even more quickly.
