'Name' => 'AwingSoft Winds3D Player SceneURL Buffer Overflow',

'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.
