To fix privately reported vulnerabilities found in almost all Internet Explorer versions including IE9, Microsoft has released a security update "KB2675157" as a part of Patch Tuesday.
The most severe vulnerabilities could allow remote code execution if a user views 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 logged-on user. Users whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights.
This security update is rated Critical for Internet Explorer 7, Internet Explorer 8, and Internet Explorer 9 on Windows clients and Moderate for Internet Explorer 7, Internet Explorer 8, and Internet Explorer 9 on Windows servers.
The security update addresses the vulnerabilities by modifying the way that Internet Explorer handles the printing of specially crafted HTML content and the way that Internet Explorer handles objects in memory.

Although its a security update, it updates version of IE9 to 9.0.6. If you check the About Internet Explorer box, it shows the "Update Versions" is 9.0.6.
You can install the update using Windows Update or download using following link:

Why they are already updating IE6?
It's too old to use it...

Nice. So they now release incremental builds in security sense like Mozilla. That`s nice.
