IIRC, it is not a legal port to connect to, but some IP implementations
react badly if you send a malformed packet which says it is destined for port
0.
A large number of DoS attacks over the years are simply due to buggy IP
implementations which get totally derailed if anything even remotely
unexpected occurs. And please note that I do include Unix and Linux in this
statement. For some reason, people seemed to assume an IP packet would never
go wrong. Thankfully, things have gotten somewhat better, but I'm still
rather astounded at some of the bugs (and exploits) people discover in such a
core piece of code.
