Re: [Full-disclosure] Apple QuickTime 0day

[Jared DeMott <jdemott () crucialsecurity com>]

Excellent.  Doesn't trigger on Mac.  I just did a talk on QuickTime
hacking at ShakaCon III -- which btw -- can I just say "best place for a
 con ever!".  My slides are at www.vdalabs.com.  The slides might give
you some insight into the types of exceptions you're hoping for.  To
boil it down, a tool like "!exploitable" is nice since it could be used
to bin crashes into "read exception" or "write exception" (the type
you're looking for).  Oh, and by the way, you can't really call a crash
an 0day.  I called them "0day crashes" in my talk, just to be clear.

Blessings,
Jared
