If one examines the original notification, this article from CERT 
(http://www.us-cert.gov/cas/techalerts/TA04-111A.html), and the 
Internet Draft that Peter Stendahl-Juvonen referenced in the first post 
of this thread, and observe the response that it has received from 
those who actually run TCP-based networks, I think one must conclude 
that this is not FUD.

Chapter 18 of Richard Stevens' book _TCP/IP_Illustrated,_Volume_1_ does 
a great job of describing how TCP connections are made and broken.  
Read that, read the documents referenced above, and then see what you 
think . . .

 idea."  -- RFC 1925
