June 11, 2019—KB4503287 (Security-only update)

Applies to: Windows Server 2008 Service Pack 2

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 Server article. (These registry settings are disabled by default for Windows Server OS editions).
  • Security updates to Windows App Platform and Frameworks, Windows Input and Composition, Windows Shell, Windows Server, Windows Authentication, Windows Datacenter Networking, Windows Storage and Filesystems, Windows Virtualization, Windows Kernel, Internet Information Services, Windows Server, and the Microsoft JET Database Engine.

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

Known issues in this update


Symptom Workaround
When trying to expand, view, or create Custom Views in Event Viewer, you may receive the error, "MMC has detected an error in a snap-in and will unload it." and the app may stop responding or close. You may also receive the same error when using Filter Current Log in the Action menu with built-in views or logs. Built-in views and other features of Event Viewer should work as expected.

To mitigate this issue, see KB4508640.

We are working on a resolution and estimate a solution will be available in late June.
