Thirteen security updates from Microsoft this month address over forty issues in Windows, Internet Explorer, Edge, Office, server software and .NET. Six are flagged as Critical.

In keeping with their recent practise of tagging along with Microsoft, Adobe also just released several updates, most notably for Flash. The latest version of Flash is now 20.0.0.306. As usual, Internet Explorer on Windows 8.1 and 10 and Edge on Windows 10 will get their new Flash via Windows Update, and Chrome will update itself with the latest Flash. The associated security bulletin gets into all the technical details. A total of 22 vulnerabilities are addressed in the new version.
