Hi,

Does this require an established TCP session to be present? - i.e. If you 
have a host which provides no external TCP sessions (i.e. replies 
'Connection Refused' / drops the initial SYN) would that still be 
potentially exploitable?

What about boxes used as routers - that just forward the traffic (and 
again, offer no TCP services directly themselves)?
