Security-only update

Improvements and fixes

This security update includes quality improvements. Key changes include:

  • Provides protections against a new subclass of speculative execution side-channel vulnerabilities, known as Microarchitectural Data Sampling, for 64-Bit (x64) versions of Windows (CVE-2019-11091,CVE-2018-12126, CVE-2018-12127, CVE-2018-12130). Use the registry settings as described in the Windows Client and Windows Server articles(These registry settings are enabled by default for Windows Client OS editions, but disabled by default for Windows Server OS editions).

  • Addresses an issue that may prevent applications that rely on unconstrained delegation from authenticating after the Kerberos ticket-granting ticket (TGT) expires (the default is 10 hours).

  • Security updates to Windows App Platform and Frameworks, Microsoft Graphics Component, Windows Storage and Filesystems, Windows Cryptography, Windows Wireless Networking, Windows Kernel, Windows Server, and the Microsoft JET Database.

For more information about the resolved security vulnerabilities, please refer to the Security Update Guide.
