Hi Oded! The Content-Length/GET trick does not work with lookaside in this case; the application allocates a huge (8018) byte chunk and then loads the network data into this. I will have to find a way to control allocation size (which shouldn't be too hard, just time consuming). Thanks for the suggestion, it might be time to go back and fix my XEXCH50 exploit as well :) -HD On Monday 30 August 2004 13:15, oded.horovitz () hushmail com wrote:
You have the best setup for lookaside basing. Just load a controllable lengthed input to some lookaside entry. and set edx to that entry-0x44
