Stack-based buffer overflow in the MOVIEPLAYER.MoviePlayerCtrl.1 ActiveX control
in MoviePlayer.ocx 6.8.0.0 in Viscom Software Movie Player Pro SDK ActiveX 6.8 allows
remote attackers to execute arbitrary code via a long strFontName parameter to the
DrawText method.
The victim will first be required to trust the publisher Viscom Software.
This module has been designed to bypass DEP and ASLR under XP IE8, Vista and Win7
with Java support.
