Security Updates

The January update also includes extremely critical security patches. Microsoft outlines all the updates in its MS16-004 Security Bulletin. In summary, the software exploits patched allow remote code execution, the most serious of all security vulnerabilities.


Here are the details directly from the Security Bulletin:

Security Update for Microsoft Office to Address Remote Code Execution (3124585)
This security update resolves vulnerabilities in Microsoft Office. The most severe of the vulnerabilities could allow remote code execution if a user opens a specially crafted Microsoft Office file. An attacker who successfully exploited the vulnerabilities could run arbitrary code in the context of the current user. Customers whose accounts are configured to have fewer user rights on the system could be less impacted than those who operate with administrative user rights.

Easiest way to install the Update

Grabbing the updates are fairly simple using Microsoft AutoUpdate for Mac. Open any of the Microsoft Office for Mac apps (Outlook, Word, etc.) and click Help > Check for Updates.

If you prefer to download the updates individually so you can package and deploy them to a corporate environment, you can update packages for Outlook, PowerPoint, Word, Excel and OneNote on the KB3133711 page.

      What did you do to fix this problem? I like to do the updates, but now I’m scared to. BTW, I was able to go back in Time Machine and go back to Excel version 15.17 and delete 15.18. So we’re now back in business.
