A further useful source of update related information is the Calendar of Updates. News/announcements of updates in the categories of General SoftwareSecurity 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.

====================
For this month’s Microsoft updates, I will prioritize the order of installation below. A useful list of all CVEs for this month is present here courtesy of BleepingComputer:
====================

CVE-2018-8267 | Scripting Engine Memory Corruption Vulnerability (a zero day (defined) vulnerability disclosed last month)

Microsoft Edge and Internet Explorer (similar to many other months; multiple versions of Edge and IE affected with many of the CVEs affecting the Microsoft Scripting Engine))

CVE-2018-8225 | Windows DNSAPI Remote Code Execution Vulnerability

CVE-2018-8231 | HTTP Protocol Stack Remote Code Execution Vulnerability (especially if your server hosts a Microsoft IIS installation)

====================
Please install the remaining updates at your earliest convenience.

As usual; 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. I have provided further details of updates available for other commonly used applications below.

Thank you.

Original Post:
=======================
I usually write this post on or very shortly after Update Tuesday (the second Tuesday) of the month but with an Adobe Flash zero day vulnerability (defined) already patched and given that Mozilla have also released an update this month; I felt an earlier post would be appropriate.

I’ll update this post as further updates are made available. Thank you.
