The intention of this article is not to teach you the in's and out's of buffer overflows, but to explain in a little detail another technique used to execute arbitrary code as opposed to the classic 'NOP sled + shellcode + repeated retaddr' method. I assume readers are familiar with buffer overflow vulnerabilities and the basics of how to exploit them. Also a little bit of the theory of memory organization is desirable, such as how the little-endian bit ordering system works. To those who are not familiar with buffer overflow bugs, I suggest you read "Smashing the Stack for Fun and Profit".
