This security update resolves seven privately reported vulnerabilities and one publicly disclosed vulnerability in Internet Explorer. The more severe vulnerabilities could allow remote code execution if a user views a specially crafted Web page using Internet Explorer.

If you have windows update configured to automatic update, the update will be downloaded automatically. You can just install it if you see the yellow shield icon popping up in the system tray in XP, and update notification in Windows Update in System and Security in Windows 7.
Or, please download the update and install it manually from this security update bulletin.
