Heap Feng Shui is the ancient art of arranging heap blocks in order to redirect
the program control flow to the shellcode. I just published the slides from my
BlackHat Europe presentation about a JavaScript implementation of this technique.

This work is an evolution of the heap spraying technique, but it allows precise
application data overwrites and reliable browser exploitation. It will be of
great interest to everybody working on client side exploitation.

The materials include slides, a paper and source code of a JavaScript heap
manipulation library.

Take care,
Alex
