Version:

Security-only update

IMPORTANT Microsoft released update KB5012170 on August 9, 2022. It provides support for Secure Boot Forbidden Signature Database (DBX). This is a standalone, security update. Windows 8.1 and newer clients and Windows Server 2012 and newer servers must install this update regardless of whether BitLocker is enabled or supported on your device. After you install the update, you might receive error “0x800f0922”; see Update might fail to install and you might receive a 0x800f0922 error. After you install the update, your device might start up in BitLocker recovery mode. See Some devices might start up into BitLocker Recovery and Finding your BitLocker recovery key in Windows.

Summary

Learn more about this security-only update, including improvements, any known issues, and how to get the update. 

IMPORTANT Windows Server 2012 has reached the end of mainstream support and is now in extended support. Starting in July 2020, there will no longer be optional releases (known as "C" or "D" releases) for this operating system. Operating systems in extended support have only cumulative monthly security updates (known as the "B" or Update Tuesday release).

Verify that you have installed the required updates listed in the How to get this update section before installing this update. 

Note For information about the various types of Windows updates, such as critical, security, driver, service packs, and so on, please see the following article. To view other notes and messages, see the Windows Server 2012 update history home page.

Improvements

This security-only update includes new improvements for the following issues:

  • Addresses an issue in which Speech and Network troubleshooters will not start.

  • Addresses an issue that might cause the Local Security Authority Server Service (LSASS) to leak tokens. This issue affects devices that have installed Windows updates dated June 14, 2022 or later. This issue occurs when the device performs a specific form of service for user (S4U) in a non-Trusted Computing Base (TCB) Windows service that runs as Network Service.

  • Enforces a hardening change that requires printers and scanners that use smart cards for authentication to have firmware that complies with section 3.2.1 of RFC 4556. If they do not comply, Active Directory domain controllers will not authenticate them. Mitigations that allowed non-compliant devices to authenticate will not exist after August 9, 2022. For more information about this change, see KB5005408.

For more information about the resolved security vulnerabilities, please refer to the Deployments | Security Update Guide and the August 2022 Security Updates.

Known issues in this update

Symptoms

Next step

Starting at 12:00 A.M. Saturday, September 10, 2022, the official time in Chile will advance 60 minutes in accordance with the August 9, 2022 official announcement by the Chilean government about a daylight saving time (DST) time zone change. This moves the DST change which was previously September 4 to September 10.

Symptoms if the workaround is not used on devices between September 4, 2022 and September 11, 2022:

  • ​Time shown in Windows and apps will not be correct.

  • ​Apps and cloud services which use date and time for integral functions, such as Microsoft Teams and Microsoft Outlook, notifications and scheduling of meetings might be 60 minutes off.

  • ​Automation that uses date and time, such as Scheduled tasks, might not run at the expected time.

  • ​Timestamp on transactions, files, and logs will be 60 minutes off.

  • ​Operations that rely on time-dependent protocols such as Kerberos might cause authentication failures when attempting to logon or access resources.

  • ​Windows devices and apps outside of Chile might also be affected if they are connecting to servers or devices in Chile or if they are scheduling or attending meetings taking place in Chile from another location or time zone. Windows devices outside of Chile should not use the workaround, as it would change their local time on the device.

To mitigate this issue, please see Possible issues caused by new Daylight Savings Time in Chile.

We are working on a resolution and will provide an update in an upcoming release.

Note We plan to release an update to support this change; however, there might be insufficient time to properly build, test, and release such an update before the change goes into effect. Please use the workaround above.

How to get this update

Before installing this update

We strongly recommend that you install the latest servicing stack update (SSU) for your operating system before installing the latest Rollup. SSUs improve the reliability of the update process to mitigate potential issues while installing the Rollup and applying Microsoft security fixes. For general information about SSUs, see Servicing stack updates and Servicing Stack Updates (SSU): Frequently Asked Questions.

If you use Windows Update, the latest SSU (KB5016263) will be offered to you automatically. To get the standalone package for the latest SSU, search for it in the Microsoft Update Catalog

REMINDER If you are using Security-only updates, you will also need to install all previous Security-only updates and the latest cumulative update for Internet Explorer (KB5016618).
