A remote code execution vulnerability exists in the way Internet Explorer instantiates COM Objects that are not intended to be used in Internet Explorer. An attacker could exploit the vulnerability by constructing a malicious Web page that could potentially allow remote code execution if a user visited the malicious Web site. An attacker who successfully exploited this vulnerability could take complete control of an affected system.
An attacker who successfully exploited this vulnerability could take complete control of the affected system. In a Web-based attack scenario, an attacker would host a Web site that exploits this vulnerability. An attacker would have no way to force users to visit a malicious Web site. Instead, an attacker would have to persuade them to visit the Web site, typically by getting them to click a link that takes them to the attacker's site. It could also be possible to display malicious Web content by using banner advertisements or by using other methods to deliver Web content to affected systems
Technical details (analysis)
When Internet Explorer tries to instantiate certain COM objects as ActiveX controls, the COM Objects may corrupt system memory in such a way that an attacker could execute arbitrary code. An attacker could host a malicious Web site that is designed to exploit this vulnerability through Internet Explorer and then persuade a user to view the Web site.
