Who is Vulnerable?
Vulnerability Description	The Microsoft Internet Explorer (IE) is the most widely used web browser application. The browser is capable of processing HTML, scripting languages and interpretation of various other popular Internet specifications. There exists a buffer overflow vulnerability in the IsComponentInstalled function of Microsoft Internet Explorer. The flaw is caused by a lack of length verfication checks of parameters passed to the affected function. A remote attacker can exploit this vulnerability by enticing a user to visit a specially crafted web page, which may lead to the injection of arbitrary code that will be executed in the security context of the current user. In an unsuccessful attack case, where the attack does not result in the flow of the process being diverted, the affected application will terminate. The behaviour of the target system after a successful attack is dependent on the intention of the injected code. In the case of arbitrary code execution, the code is executed within the security context of the current user.
