Re: denial of service attack possible

[jas () flyingfox COM (Jim Shankland)]

[Denial of service possible by remote host putting multiple connections
to a port into the SYN_RCVD state, thereby precluding further
(legitimate) connection attempts.]

It's even worse.  The same thing was done deliberately by Kevin Mitnick
during his packet-spoofing attack on Shimomura's machines in San Diego.
Mitnick put lots of connections into the SYN_RCVD state on machine A,
thereby "jamming" machine A and preventing it from interfering
(by sending RST packets) with his attack on machine B, impersonating
machine A.
