Who is Vulnerable?
Vulnerability Description Microsoft Internet Explorer (IE) is the most widely used web browser application. The browser is capable of processing HTML, images, scripting languages, and various other popular Internet specifications. The browser is also compatible with Microsoft's Common Object Model (COM) scheme, whereby applications can register a library or an executable that provides a general interface to other applications in the system. Any application can then instantiate a COM object without knowing many details about its behavior or requirements. There exists a heap memory corruption vulnerability in the Microsoft Internet Explorer browser. The flaw is caused by an improper check during processing of a specially crafted Image property of a specific HTML Help Control ActiveX Object. An attacker can exploit this vulnerability to inject and execute arbitrary code in the security context of the currently logged in user. In case of an attack where code injection is unsuccessful, the affected browser will terminate. In case of an attack where code injection is successful, the behavior of the host system is dependent on the intented purpose of the injected code. The injected code will be run in the security context of the currently logged in user.
