Exploiting heap overflows on XP SP2

Subject: Exploiting heap overflows on XP SP2
Date: 18 Aug 2005 08:18:33 -0000
Hi,

I describe a new way to exploit heap-based buffer overflows in the following 
paper:

http://www.packetstormsecurity.com/papers/bypass/bypassing-win-heap-protections.pdf

Basically, one can use critical section related linking structures stored on 
the process?s default heap to produce a n*4-byte overwrite. Gaining control is 
another problem, only memory overwrite is discussed in the paper.
