As you know Microsoft and Adobe released their scheduled monthly security updates. For Microsoft this release was anticipated especially since last month’s set was delayed.
Within the above linked to post I predicted Microsoft would make a large number of updates and they did just that. 17 bulletins in total are now available. These updates address 138 vulnerabilities listed within Microsoft’s new Security Update Guide. These vulnerabilities are more formally known as CVEs (defined).
Once again; there are no Known Issues listed within their March summary page. At the time of writing the IT Pro Patch Tuesday blog does not list any Known Issues. However, please check it before deploying your security updates just to be sure. As always, if any issues do arise, those pages should be your first places to check for solutions.
Adobe issued two security bulletins today. One affecting Adobe Flash and the other for Adobe Shockwave Player. The Flash Player bulletin resolves 7x priority 1 vulnerabilities. While the Shockwave bulletin resolves 1x priority 2 vulnerability. These priority rating are explained in the previous link.
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 made available last week.
If you use Flash or Adobe Shockwave, please review the security bulletins linked to above and apply the necessary updates. The Flash update should be installed as soon as possible since exploit kits (defined) tend to take advantage of newly disclosed vulnerabilities very quickly.
You can monitor the availability of security updates for most 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):
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 donating.
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.
Update: 22nd March 2017:
I wish to provide information on other notable updates from this month which I would recommend you install if you use these software products:
Notepad++ version 7.3.3
VideoLAN VLC Media version 2.2.5 (release currently in progress)
Malwarebytes Anti-malware version 3.0.6 CU3 (with Component package version: 1.0.75):
It is unknown how many vulnerabilities this addresses but this forum post mentions their resolution.
More details of the vulnerabilities resolved by Malwarebytes 3.0.6 CU3 have emerged. Researchers responsibly disclosed a technique which uses Microsoft’s Application Verifier to hijack an anti-malware application. More details of this vulnerability are available here and here.
Mozilla Firefox 52.0.1 (more details in this post on Pwn2Own 2017)
VMware Workstation 12.5.4 (relevant security advisories are here and here)
Wireshark 2.2.5 and 2.0.11
Putty 0.68 (while released in February; it contains important security changes)
For the 17 Microsoft bulletins this month, I will prioritize the order of updates for you below:
Windows Graphics Component
Windows SMB Server
The update for Microsoft Office should be installed next due to it’s criticality. With the follow updates after it:
Active Directory Federation Server
As always you can find 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 5.52) 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 will be out of support on the 31st of July 2018.
As is my standard practice, I would recommend backing up the data on any device for which you are installing updates to prevent data loss in the rare event that any update causes unexpected issues.
