of arbitrary code." );

"Macrovision FLEXnet Connect, formerly known as InstallShield Update Service, is installed on the remote host.  It is a
software management solution for internally-developed and third-party applications, and may have been installed as part
of the FLEXnet Connect SDK, other InstallShield software, or by running FLEXnet Connect-enabled Windows software.

The version of the FLEXnet Connect client on the remote host includes an ActiveX control -- the InstallShield Update
Service Agent -- that is marked as 'safe for scripting' and contains several methods that allow for downloading and
launching arbitrary programs.  If a remote attacker can trick a user on the affected host into visiting a specially
crafted web page, this issue could be leveraged to execute arbitrary code on the host subject to the user's privileges.

Additionally, it is reportedly affected by a buffer overflow that can be triggered by passing a long argument for
'ProductCode' to the 'DownloadAndExecute()' method.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number." );
