Building ROP chains to defeat data execution prevention - DEP. This series is about exploiting simple stack overflow vulnerabilities using return oriented programming (ROP) to defeat data execution prevention - DEP. There are three posts in this series. The posts got pretty dense, there is a lot of stuff to understand. If you miss anything, find bugs (language / grammar / ...), have ideas for improvements or any questions, do not hesitate to contact (via Twitter or contact page) me. I am happy to answer your questions and incorporate improvements in this post.
