November 2016 Security Updates Summary

Earlier today Microsoft and Adobe released their scheduled monthly security updates.

Microsoft’s made available many bulletins, 14 in total. These updates address 67 vulnerabilities listed within Microsoft’s security bulletin summary (as before excluding the Adobe bulletin). These are more formally known as CVEs (defined).

Once again this month (so far) there are no Known Issues detailed within the above mentioned summary page. Monitoring this page before deploying the updates as well as the IT Pro Patch Tuesday blog will keep you well informed enabling you to have the best opportunity to avoid potential issues. If any issues do arise, those pages should be your first places to check for solutions.

====================

Today Adobe made available one other security bulletin by Adobe affecting Adobe Connect (resolving 1x priority 3 issue) in addition to their regular Flash Player update. Depending on which version of Flash Player you have, please review the Adobe security bulletin or Microsoft bulletin as appropriate and apply the recommended updates. Google Chrome users will have the updated installed automatically alongside the updated version of Google Chrome which was made available very shortly after Adobe’s update.

The Flash Player update addresses 9 priority 1 CVEs. If you use either of these products, please review the security bulletins linked to above and apply the necessary updates.

You can monitor the availability of security updates for the majority of your software from the following websites (among others) or use Secunia PSI:

—————
US Computer Emergency Readiness Team (CERT) (please see the “Information on Security Updates” heading of the “Protecting Your PC” page):

https://www.us-cert.gov/

A further useful source of update related information is the Calendar of Updates.

News/announcements of updates in the categories of General Software, Security Software and Utilities are available on their website. The news/announcements are very timely and (almost always) contain useful direct download links as well as the changes/improvements made by those updates (where possible).

If you like and use it, please also consider supporting that entirely volunteer run website by making a donation.

If you use any of the above software, please install the appropriate updates as soon as possible. Steps for installing updates for Windows are provided on the “Protecting Your PC” page.

To assist with making the best use of your time when deploying these updates, I will prioritise the updates for you below:

This month the previously disclosed zero day (defined) vulnerability under attacker should take first priority, it is addressed in MS16-135 Next, please prioritise the deployment of the following updates:

Microsoft Internet Explorer, Microsoft Edge, Microsoft Graphics Component , Microsoft Office, Microsoft Video Control and the Windows Security Update bulletin.

Businesses and enterprise should priorities the deployment of the SQL Server update since it addresses 6 important vulnerabilities.

As always Adobe’s Flash Player update (to version 23.0.0.207) should also be on your shortlist this month.

The remaining security updates can be installed when you have the time to do so. Detailed information on the contents of each security bulletin is published each month within ComputerWorld’s Patch Tuesday Debugged column.

Another security pre-caution that you may wish to take if you have Microsoft EMET (please ensure your version of EMET is the most recent version 5.5) installed is to use it to protect you from Adobe Flash being used to exploit vulnerabilities when you open a Microsoft Office document or Adobe PDF file. I provide recommendations of how to do this at the end of the July 2015 Update Summary.

Please note that Microsoft EMET is in the process of being retired with the end of support scheduled for the 31st of July 2018.

As always as a routine precaution I would recommend backing up the data on any device for which you are installing updates in order to prevent data loss in the rare event that any update causes unexpected issues.

Thank you.
