Researchers have posted "proof of concept" code that can take advantage of vulnerabilities in Windows platforms. The concept code works against vulnerabilities in the Windows help subsystem and in code used to load desktop icons and the Windows help subsystem. Even systems with Windows XP with Service Pack 2 are affected as Internet Explorer can be used as a vector in exploits. Systems could become compromised without any user interaction if a user simply visits a malicious Web page.

At least one exploit has already been released into the wilds of the Internet. No patches are available yet for these newly reported problems. Administrators can help protect their networks by ensuring that their intrusion prevention systems are update to date.
