Hi dear readers, Rhys Kidd a écrit :
So what does Microsoft provide to make this more secure? Firstly the push by Michael Howard et al to get ASLR implemented in Vista beta 2 and above means the addresses within ntdll.dll are going to be somewhat random, thereby making reliable use of this technique difficult. NX bit based defenses really should be implemented hand-in-hand with some form of memory randomisation, as was documented by the PaX project.
Put me in my place if I'm wrong, but adresses are only randomized once at boot up, making the Vista randomization far less effective than a run time randomization a la PaX. Well, at least, thats what I understood from the Microsoft TechDays in Paris 2 weeks ago.
Secondly, as Dave mentioned setting "AlwaysOn" in boot.ini should prevent DEP from being disabled on a per-process basis. HTH. Rhys
