					This module exploits a stack based overflow vulnerability in the handling
				of the DXF files by Microsoft Visio 2002. Revisions prior to the release of
				the MS bulletin MS10-028 are vulnerable. The overflow occurs when the application
				is used to import a specially crafted DXF file, while parsing the HEADER section
				of the DXF file.

				To trigger the vulnerability an attacker must convince someone to insert a
				specially crafted DXF file to a new document, go to 'Insert' -> 'CAD Drawing'
