					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.  The flaw is
				generally known as a bug while processing the 'transform' attribute, however,
				that attack vector seems to only cause a TerminateProcess call due to a corrupt
				stack cookie, and more data will only trigger a warning about the malformed XML
				file.  This module exploits the 'color' value instead, which accomplishes the same
				thing.
