Microsoft Internet Explorer fails to properly handle requests to mismatched DOM objects, which may allow a remote attacker to execute arbitrary code on a vulnerable system.
Microsoft Internet Explorer does not properly handle requests to mismatched DOM objects, such as the window() object. When an HTML document references a DOM object in a specially crafted manner, Internet Explorer can crash in a way that allows an attacker to execute arbitrary shell code.
Note: Proof of concept code is publicly available. This vulnerability is being actively exploited to spread malicious software such as Win32/Delf.DH and Troj/Clunky-B.
By convincing a user to view a specially crafted HTML document (e.g., a web page, an HTML email message, or an HTML email attachment), an attacker may be able to execute arbitrary code with the privileges of the user. The attacker could also cause IE (or the program using the WebBrowser control) to crash.
