CSCed38527

A vulnerability in the Transmission Control Protocol (TCP) specification (RFC793) has been 
discovered by an external researcher. The successful exploitation enables an adversary to reset any 
established TCP connection in a much shorter time than was previously discussed publicly. 
Depending on the application, the connection may get automatically re-established. In other cases, 
a user will have to repeat the action (for example, open a new Telnet or SSH session). Depending 
upon the attacked protocol, a successful attack may have additional consequences beyond 
terminated connection which must be considered. This attack vector is only applicable to the 
sessions which are terminating on a device (such as a router, switch, or computer) and not to the 
sessions that are only passing through the device (for example, transit traffic that is being routed by 
a router). In addition, this attack vector does not directly compromise data integrity or 
confidentiality. 

All Cisco products which contain TCP stack are susceptible to this vulnerability. 

This advisory is available at 

 

and it describes this vulnerability as it applies to Cisco products that run Cisco IOS® software. 

A companion advisory that describes this vulnerability for products that do not run Cisco IOS 
software is available at
