'Name' => 'VeryTools Video Spirit Pro <= 1.70',
'Description' => %q{
This module exploits a stack buffer overflow in Video Spirit <= 1.70.
When opening a malicious project file (.visprj), a stack buffer overflow occurs,
resulting in arbitrary code execution.
This exploit bypasses DEP & ASLR, and works on XP, Vista & Windows 7.
