I have been writing a number of tutorials on my blog about how to create buffer overflow exploits using BackTrack.
I posted the links to parts one and two on the old forums, and I just finished part three, so I decided to post links to all three parts here.
I will update this post with more links when I write further entries.
Part One: A Simple Windows Stack Based Buffer Overflow
Part Two: A Windows Stack Based SEH Buffer Overflow
Part Three: A Windows Stack Based SEH Buffer Overflow with Character Translation
Part Four: A Windows Use After Free Heap Corruption Exploit
Part Five: A Windows Stack Based Overflow using an Egghunter and a Conditional Jump
Update: Added link to part four.
Update: Added link to part five.
