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.
