Software giant Microsoft plans to ship seven bulletins in the March 2013 edition of Patch Tuesday. Four of the bulletins are receiving high-severity, critical ratings. Three of the four critically rated bulletins that affect Microsoft Windows, Internet Explorer, Silverlight, Office, and Server Software could lead to remote code execution. The less severe, important-rated bulletins affect Office, Server Software, and Windows. The Patch Tuesday notification will go live, replacing the advanced bulletins, on March 13 at 1 PM EST.
