What is Affected?

The vulnerability described in this advisory affects implementations of the Transmission Control Protocol (TCP) that comply with the Internet Engineering Task Force’s (IETF’s) Requests For Comments (RFCs) for TCP, including RFC 793, the original specification, and RFC 1323, TCP Extensions for High Performance.

TCP is a core network protocol used in the majority of networked computer systems today. Many vendors include support for this protocol in their products and may be impacted to varying degrees. Furthermore any network service or application that relies on a TCP connection will also be impacted, the severity depending primarily on the duration of the TCP session.
