Improvements and fixes
This security update includes improvements and fixes that were a part of update KB4592484 (released December 8, 2020) and addresses the following issues:
- Addresses a security bypass vulnerability that exists in the way the Printer Remote Procedure Call (RPC) binding handles authentication for the remote Winspool interface.
- Addresses a security vulnerability issue with HTTPS-based intranet servers. After you install this update, HTTPS-based intranet servers cannot leverage a user proxy to detect updates by default. Scans that use these servers will fail if the clients do not have a configured system proxy.
- If you must leverage a user proxy, you must configure the behavior by using the Windows Update policy Allow user proxy to be used as a fallback if detection using system proxy fails. To make sure that the highest levels of security, additionally leverage Windows Server Update Services (WSUS) Transport Layer Security (TLS) certificate pinning on all devices.
- Note This change does not affect customers who use HTTP WSUS servers.
- Addresses an issue in which a principal in a trusted Managed Identity for Application (MIT) realm does not obtain a Kerberos Service ticket from Active Directory domain controllers (DCs). This issue occurs after Windows Updates that contains CVE-2020-17049 protections released between November 10 and December 8, 2020 are installed and PerfromTicketSignature is configured to 1 or higher. Ticket acquisition fails with KRB_GENERIC_ERROR if callers submit a PAC-less Ticket Granting Ticket (TGT) as an evidence ticket without providing the USER_NO_AUTH_DATA_REQUIRED flag.
- Security updates to Windows App Platform and Frameworks, Windows Graphics, Windows Media, Windows Fundamentals, Windows Cryptography, and Windows Virtualization.

Microsoft's 'Blue' wave of tools and technologies is more than just a user interface refresh. It's the next step on Microsoft's journey to becoming a devices and services company, and the first of what the company intends to be a regular series of updates to its core platform. At the heart of that core platform is Windows Server, the foundation for Azure and for what Microsoft calls its Cloud OS. All of which means that Windows Server 2012 R2 is much more than just another service pack; adding new features that make it easier to build cloud applications and services in your datacentre, and to move them to and from Azure.

Windows Server 2012 R2 introduces lots of small changes in some key areas, which all together add up to make the server OS update an even more robust and scalable operating system.
