Microsoft Black Tuesday: Security Flaws in a Menagerie of Products

Though today’s Patch Day might seem pretty average as far as the number of security bulletins released, it does cover a rather eclectic range of Microsoft products. In fact, a few of the updates affect Mac users as well, and one is even exclusive to Mac.

During today’s Patch Day, Microsoft released seven security bulletins fixing  20 vulnerabilities in the following products:

  •  Windows (all versions)
  • Internet Explorer (IE)
  • Office Suite updates
    • Visio Viewer 2010
    • SharePoint Server 2010
    • OneNote 2010
    • Office Outlook for Mac
  • Silverlight 5 (For PC and Mac)

They rate four of the bulletins as Critical, and three as Important. Many of the Critical issues can allow remote attackers to execute code on affected systems. So we highly recommend you patch them quickly.

We’ll share more details about today’s bulletins in upcoming alerts. Until then, feel free to check out Microsoft’s March bulletin summary.  — Corey Nachreiner, CISSP (@SecAdept)
