I already banged my head at this, but didn't come very far:

Did somebody got a working exploit (one commit mentions
this should be easily exploitable via nmap) yet?

I admit I'm not very good at creating RAW
IP-Packets, I tried to start with these
example wireshark captures:
http://wiki.wireshark.org/SampleCaptures#Stream_Control_Transmission_Protocol_.28SCTP.29

I would also be interested in tutorials
or other literature (links) which
provide information how to create
raw IP-Packets in general and how to
manipulate their content.

My goals are to better understand these
issues and to do some pentesting on
my own infrastructure, plus maybe
test for some other possible protocol
implementation weaknesses in the linux kernel.

I know this is a little of topic, so
you can also reply off list, if you wish.

kind regards and thanks in advance.

Sven
