Cisco yesterday reported a vulnerability with some implementations of the Transmission Control Protocol (TCP) Timestamps option (RFC1323) are vulnerable to a Denial of Service (DoS) attack from specifically crafted packets. Cisco also states that only certain implementations of the TCP Timestamps option are vulnerable.
