A critical vulnerability was identified in Microsoft Internet Explorer, which could be exploited by remote attackers to execute arbitrary commands. This issue is due to a memory corruption error when instantiating the "Msdds.dll" (Microsoft Design Tools Diagram Surface) object as an ActiveX control, which could be exploited by an attacker to take complete control of an affected system via a specially crafted Web page.
Note : The affected library is installed with Microsoft Office and Microsoft Visual Studio. Only systems where the "Msdds.dll" library is installed are vulnerable.
This vulnerability has been confirmed on Windows XP SP2 with Internet Explorer 6 and msdds.dll version 7.0.9064.9112.
Note : A fully functional exploit has been released.
