Microsoft announced that it will release nine bulletins, addressing 21 vulnerabilities in Microsoft Windows, Office, Internet Explorer, .NET framework and Silverlight. The patch release date is scheduled to be released February. 14.

According to the Advanced Notification, four of the bulletins are listed as “critical”.  Three will affect Windows and require a restart. The critical bulletins address errors in Windows, Internet Explorer and server-side software, and they address vulnerabilities that would allow remote code execution.

The remaining five bulletins are listed as “important” and deal with both remote code execution and elevation of privileges, involving Microsoft Widows, Office and Server Software. Only one of those will require a computer or server restart.

In addition,  the Microsoft Windows Malicious Software Removal Tool would be updated on Windows Update, Microsoft Update, Windows Server Update Services, and the Download Center.
