BTW, tested the POC on MSIE (File Version = 6.00.2900.2180 (xpsp_sp2_rtm.040803-2158)) with mshtml.dll (6.00.2900.2802 (xpsp_sp2_gdr.051123-1230)) and it didn't worked.
Daniel followed up with me in private and confirmed that the PoC *did* work for him when he followed certain additional instructions: because the attack depends on memory layout and usage, to get consistent results, be sure to close *all* MSIE windows, then go to Start -> Run... and type: iexplore http://lcamtuf.coredump.cx/iedie.html That should crash the browser immediately, because there are no other buffers nearby to "absorb" the initial fencepost. Still, if no dice, try hitting 'Reload' a couple of times. /mz _______________________________________________ Full-Disclosure - We believe in it.
