Who is Vulnerable?
Vulnerability Description Microsoft Internet Explorer allows HTML documents to embed ActiveX controls for the authoring of dynamic web content. ActiveX controls are based on Component Object Model (COM) technologies. There exists a vulnerability in the way Microsoft Internet Explorer instantiates certain COM objects that are not designed to be used as ActiveX controls. When such a COM object is instantiated by Internet Explorer, the application memory can be corrupted. Successful exploitation of this vulnerability can allow for arbitrary code execution within the privileges of the currently logged in user. In a simple attack case, the affected Internet Explorer will terminate immediately when the malicious page is opened. In a sophisticated attack scenario, where the malicious user is successful in injecting and executing supplied code, the behaviour of the system is dependent on the nature of the injected code. Any code injected into the vulnerable component would execute in the security context of the currently logged in user.
