Re: Apple QuickTime 0day

Hi WebDEVIL,

You base your PoC on this plugin (http://www.codeplex.com/msecdbg) for
windbg (as copy/pasted), but i wonder, what make you think it's really
exploitable (on quicktime) ?
Have you tried that PoC on Itunes ?
Itunes, use Quicktime as a module to read .mov files, but Itunes doesn't
have the same memory protection than Quicktime, for example see :
http://milw0rm.com/exploits/7296 , it still works on the last one today
[Itunes 8.2.0.23]

What do you get with your Poc when you play with it on Itunes ?

Thanks
