'Name' => 'Apple QuickTime 7.6.7 _Marshaled_pUnk Code Execution',
'Description' => %q{
This module exploits a memory trust issue in Apple QuickTime
7.6.7. When processing a specially-crafted HTML page, the QuickTime ActiveX
control will treat a supplied parameter as a trusted pointer. It will
then use it as a COM-type pUnknown and lead to arbitrary code execution.
This exploit utilizes a combination of heap spraying and the
QuickTimeAuthoring.qtx module to bypass DEP and ASLR. This module does not
opt-in to ASLR. As such, this module should be reliable on all Windows
versions.
NOTE: The addresses may need to be adjusted for older versions of QuickTime.
