Who is Vulnerable?
Vulnerability Description	Microsoft Internet Explorer 6 (IE6) is the sixth major revision of Internet Explorer, a web browser developed by Microsoft for Windows operating systems. It was released on August 27, 2001. It is the default browser shipped with Windows XP and Windows Server 2003, and was also made available for Windows NT 4.0, Windows 98, Windows ME, and Windows 2000. Although IE6 has now been superseded by newer versions of Internet Explorer, Microsoft still supports it in Windows 2000 SP4 and Windows XP SP3. This version of Internet Explorer is widely known for its security issues and lack of support for modern web standards. Campaigns have been established to encourage users to upgrade to newer versions of Internet Explorer or switch to different browsers, and some websites have dropped support for IE6 entirely. There are cases in which certain traffic, although not intended for malicious use, is very unsafe, since it may transfer shellcode which is undetectable by IPS.
