IE 9.0.5 Available via Windows Update along with latest critical security patches
Microsoft released an update for IE that fixes 5 privately reported vulnerabilities in Internet Explorer. One of the severe vulnerabilities could allow remote code execution if a user visits a specially crafted Web page using Internet Explorer.
"An attacker who successfully exploited any of these vulnerabilities could gain the same user rights as the local user. Microsoft rates this update critical for Internet Explorer Windows Clients, except IE6 client, where it is rated Moderate." says Microsoft
The update brings IE9 to 9.0.5 version. People who have automatic updates on need not to do any thing. If you have disabled automatic updates then you need to turn it on for this update
