Para ello tendremos que indicar el tipo del valor que vamos a modificar, por ejemplo IP_SRC_ASC_ZERO, el offset para saber donde buscarlo en el payload y la longitud del cambio, en este caso 8 bytes. Para ver un ejemplo con un payload para SIP podeis verlo en el blog de labs.mudynamic.

I've been through Kolmogrov Complexity in misguided attempts to use KC for bounding syntax processing, to various models of computation to bound the parser and semantics of the code. I have to say, great insight on your part pulling this together, my hat's off to you :) Have you considered using Betti numbers to come up with a figure of merit for a fuzzing suite?

But if you want to render it in HTML you could be interested by the PURE library. http://beebole.com/pure Thanks for the monad's post. I'm still trying to figure out how I could use it.

I also want to emphasis the word done by Chris Double at http://www.bluishcoder.co.nz, it was really enjoyable watching his efforts at the time. I applaud this effort.

It's one of the messier basic formats to get right, so it's a decent challenge for a parser. :-) The CSV demo parser doesn’t support quoted values with ” in them (quoted as “” — see http://rfc.roxen.com/4180 for the text/csv specs’ full details), though.
