An older presentation on a 'new' topic

Back in 2005 I gave this presentation at Black Hat Japan:

This year a number of security researchers have done work on the topic and are making the rounds with their presentations.

Just a few days ago there was a big to do about security vulnerabilities in ruby. The primary vulnerabilities were integer overflows affecting memory allocations in Array and String. However, it was pointed out to ruby-core in early 2006 that integer overflow issues existed in Array and that the memory allocation macros used through out the interpreter code were subject to integer overflows:

Great to see the communities getting ahead of the curve :/
