Microsoft Patches 120 Vulnerabilities, Two Zero-Days

CVEs patched this month cover Microsoft Windows, Edge (EdgeHTML-based and Chromium-based), ChakraCore, Internet Explorer, Microsoft Scripting Engine, SQL Server, .NET Framework, ASP.NET Core, Office and Office Services and Web Apps, Windows Codecs Library, and Microsoft Dynamics.
