Who is Vulnerable?
Vulnerability Description Microsoft Internet Explorer (IE) is a web browser application that is capable of rendering both static and dynamic web content. The application is primarily used for tasks related to web browsing, such as displaying HTML encoded pages, downloading files, etc. There exists a heap buffer overflow vulnerability in Microsoft Internet Explorer. The vulnerability is due to improper validation of the length value passed to a certain method call to an HTML object. Remote attackers can exploit this vulnerability by persuading target users to visit a specially crafted web page. Successful exploitation may allow the attacker to execute arbitrary code on the vulnerable client system, in the context of the logged in user. In case of an attack where code injection and execution is successful, the behavior of the target is entirely dependent on the intended function of the injected code. The code in such a case would execute within the security context of the current user. In case of an attack where code injection is not successful, Internet Explorer may terminate abnormally.
