[German]On May 12, 2020, Microsoft released security updates for Windows clients and servers, for Office, Internet Explorer, etc. Here you will find a compact overview of these updates.
A list of the updates can be found on this Microsoft page. Details about the update packages for Windows, Office, etc. are available in separate blog posts.
Servicing Stack Updates
Microsoft now publishes an overview of all current Servicing Stack Updates (SSUs). The list of SSUs can be found under ADV990001 (it is not always up to date, but we have SSU KB4555449 for Windows 7).
Notes on the updates
All Windows 10 updates are cumulative. The monthly patchday update includes all security fixes for Windows 10 and all non-security related fixes until the patchday. In addition to the security patches for the vulnerabilities, the updates contain defense-in-depth updates to improve security.
Windows 7 SP1 has been out of support since January 2020. Only customers with an ESU license (or bypass measures) will still receive updates. Updates can also be downloaded from the Microsoft Update Catalog. The updates for Windows RT 8.1 and Microsoft Office RT are only available through Windows Update.
Information about the support period for Windows 10 can be found in the Windows Lifecycle Facts Sheet. But Microsoft postphoned the end of life for Windows 10 Version 1709 (Enterprise/Education) and Windows 10 Version 1809 (Home and Pro) until October 2020, due to the corona crisis.
The May 2020 security updates cover 123 vulnerabilities in Microsoft products. 16 fixes are rated critical, 95 important and six moderate or low. A list of all security updates including CVEs can be found on the Zero Day Initiative blog. Talos has also published a summary here (details are covered separately in blog posts here).
Also note the discussion here (German). When trying to install the .NET framework update KB4556399, some users get the error code 643.
