Automated exploits from patches

“The automatic patch-based exploit generation problem is: given a program P and a patched version of the program P’, automatically generate an exploit for the potentially unknown vulnerability present in P but fixed in P’. In this paper, we propose techniques for automatic patch-based exploit generation, and show that our techniques can automatically generate exploits for vulnerable programs based upon patches provided via Windows Update.

In many cases we are able to automatically generate exploits within minutes or less.”
