February 2012 Patch Tuesday to address 21 vulnerabilities

Microsoft plans to fix coding errors in Internet Explorer, .NET Silverlight and Microsoft Office.

Microsoft is planning to release nine bulletins, addressing 21 vulnerabilities in Microsoft Windows, Office, Internet...

Explorer, .NET framework and Silverlight. The patches are scheduled to be released Feb. 14.

The software giant said in its Advanced Notification today that four of the bulletins are listed as “critical,” and three of those, all of which affect Windows, will require a restart. The critical bulletins address errors in Windows, Internet Explorer and server-side software. They all are said to 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. They apply to Microsoft Widows, Office and Server Software. Only one of those will require a restart, while the other four may require a restart.

The February Advanced Notification also stated that the Microsoft Windows Malicious Software Removal Tool would be updated on Windows Update, Microsoft Update, Windows Server Update Services, and the Download Center.

Microsoft’s Trustworthy Computing Security Response Communications Manager, Angela Gunn, said details about risk, impact analysis, deployment guidance and a video overview of the release would be available on their blog Tuesday.

In January, Microsoft released 7 bulletins, with only one listed as “critical.” They addressed problems in Microsoft Windows and Microsoft developer tools.
