Microsoft today has released this month's security updates. A total of nine security bulletins have been released, of which four address vulnerabilities with a maximum severity rating of critical. This means that at least one Microsoft product is affected critically by the vulnerability. Six bulletins fix issues in the Windows operating system, two in Microsoft Office and one each in Internet Explorer, Microsoft Server Software, Microsoft Silverlight and the Microsoft .Net Framework.
Both Windows 7 and Windows Vista are affected by four critical and one important vulnerability each, while Windows XP is only affected by three critical and two important vulnerabilities.
Here are the bulletins for February 2012:
You can access the bulletin summary here on this page.
Windows Update has already picked up the new updates. You may need to run a manual check for updates though. Windows Vista and Windows 7 users can open the control panel either by pasting Control Panel\All Control Panel Items\Windows Update into an Explorer window, or by searching for Windows Update in the start menu.
A click on Check for Updates there retrieves the most recent update information from Microsoft.
Users who do not want to or cannot update via Windows Update find all security updates at Microsoft's official download repository.
Update: Microsoft has posted the Bulletin Deployment Priority chart and the Severity and Exploitability Index. Images below.
You can read up on this month's bulletins at the Microsoft Security Response Center.
Update: The February 2012 Security Release ISO Image is available now as well.Advertisement
