A remote code execution vulnerability exists in the way Internet Explorer instantiates COM objects that are not intended to be instantiated in Internet Explorer. An attacker could exploit the vulnerability by constructing a specially crafted Web page that could potentially allow remote code execution if a user visited the specially crafted Web site.
An attacker who successfully exploited this vulnerability could take complete control of an affected system.
Technical details (analysis)
When Internet Explorer tries to instantiate certain COM objects as ActiveX Controls, the COM objects may corrupt the system state in such a way that an attacker could execute arbitrary code. Particularly, a COM object that is instantiated within IE, can take advantage of a vulnerability that IE was never meant to run this COM object as an ActiveX control.
