hi,

runix: the w00w00 heap tut will not help him.
first the windows heap structure is different from the linux oder bsd heaps.
and second the w00w00 heap tut is about bss heap stuff, not malloc/free heap
exploitation.

one paper i know about windows heap exploits was presented by david
litchfield on
blackhat windows 2004:

http://www.blackhat.com/presentations/win-usa-04/bh-win-04-litchfield/bh-win-04-litchfield.ppt

and the sample code:

http://www.blackhat.com/presentations/win-usa-04/bh-win-04-litchfield/bh-win-04-litchfield-code.rtf

another nice paper on how to exploit a windows rpc heap bug was written by
dave aitel.

hope that helps.

cheers,
