Summary

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

REMINDER Windows 8.1 will reach end of support on January 10, 2023, at which point technical assistance and software updates will no longer be provided. If you have devices running Windows 8.1, we recommend upgrading them to a more current, in-service, and supported Windows release. If devices do not meet the technical requirements to run a more current release of Windows, we recommend that you replace the device with one that supports Windows 11.

Microsoft will not be offering an Extended Security Update (ESU) program for Windows 8.1. Continuing to use Windows 8.1 after January 10, 2023 may increase an organization’s exposure to security risks or impact its ability to meet compliance obligations.

For more information, see Windows 8.1 support will end on January 10, 2023.

Windows Server 2012 R2 will reach end of support on October 10, 2023 for Datacenter, Essentials, Embedded Systems, Foundation, and Standard.

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 8.1 and Windows Server 2012 R2 update history home page.

Improvements

This cumulative security update includes improvements that are part of update KB5018474 (released October 11, 2022) and includes key changes for the following:

  • Addresses a Distributed Component Object Model (DCOM) authentication hardening issue to automatically raise authentication level for all non-anonymous activation requests from DCOM clients. This will occur if the authentication level is less than RPC_C_AUTHN_LEVEL_PKT_INTEGRITY.

  • Updates the daylight-saving time (DST) for Jordan to prevent moving the clock back 1 hour on October 28, 2022. Additionally, changes the display name of Jordan standard time from “(UTC+02:00) Amman” to “(UTC+03:00) Amman”.

  • Addresses an issue where Microsoft Azure Active Directory (AAD) Application Proxy Connector cannot retrieve a Kerberos ticket on behalf of the user because of the following general API error: “The handle specified is invalid (0x80090301).”

  • Addresses an issue where, after installing the January 11, 2022 or later update, the Forest Trust creation process fails to populate the DNS name suffixes into the trust information attributes.

  • Addresses an issue where the Microsoft Visual C++ Redistributable Runtime does not load into the Local Security Authority Server Service (LSASS) when Protected Process Light (PPL) is enabled.

  • Addresses security vulnerabilities in the Kerberos and Netlogon protocols as outlined in CVE-2022-38023, CVE-2022-37966, and CVE-2022-37967. For deployment guidance, see the following articles:

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

Known issues in this update

Symptom

Next step

After this update or a later Windows update is installed, domain join operations might be unsuccessful and error "0xaac (2732): NERR_AccountReuseBlockedByPolicy" occurs. Additionally, text stating "An account with the same name exists in Active Directory. Re-using the account was blocked by security policy" might be displayed.

Affected scenarios include some domain join or re-imaging operations where a computer account was created or pre-staged by a different identity than the identity used to join or re-join the computer to the domain.

For more information about this issue, see KB5020276—Netjoin: Domain join hardening changes.

Note Consumer Desktop editions of Windows are unlikely to experience this issue.

This issue is resolved in KB5023765.

After installing Windows updates released on or after November 8, 2022 on Windows Servers that use the Domain Controller role, you might have issues with Kerberos authentication. This issue might affect any Kerberos authentication in your environment. Some scenarios which might be affected:

When this issue is encountered you might receive a Microsoft-Windows-Kerberos-Key-Distribution-Center Event ID 4 error event in the System section of the event log on your Domain Controller with the below text.

Note Affected events will contain "the missing key has an ID of 1" string:

While processing an AS request for target service <service>, the account <account name> did not have a suitable key for generating a Kerberos ticket (the missing key has an ID of 1). The requested etypes : 18 3. The accounts available etypes : 23 18 17. Changing or resetting the password of <account name> will generate a proper key.

Note This issue is not an expected part of the security hardening for Netlogon and Kerberos starting with November 2022 security update. You will still have to follow the guidance in these articles even after this issue is resolved.

Windows devices used at home by consumers or devices which are not part of an on-premises domain are not affected by this issue. Azure Active Directory environments that are not hybrid and have no on-premises Active Directory servers are not affected.

This issue is addressed in update KB5021653.

After installing this update or a later update on a domain controller (DC), you might experience a memory leak with the Local Security Authority Subsystem Service (LSASS,exe). Depending on the workload of your DC and the amount of time since the last restart of the server, LSASS might continually increase memory usage with the up time of the server and the server might become unresponsive or automatically restart.

Note The out-of-band updates for DCs released November 17, 2022 and November 18, 2022 might be affected by this issue.

To mitigate this issue, open a Command Prompt as an Administrator and use the following command to set the registry key KrbtgtFullPacSignature to 0:

reg add "HKLM\System\CurrentControlSet\services\KDC" -v "KrbtgtFullPacSignature" -d 0 -t REG_DWORD

Note After this known issue is resolved, you should set KrbtgtFullPacSignature to a higher setting, depending on what your environment will allow. We recommend that you enable Enforcement mode as soon as your environment is ready.

For more information about this registry key, please see KB5020805: How to manage Kerberos protocol changes related to CVE-2022-37967.

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

After installing this update, apps which use ODBC connections through Microsoft ODBC SQL Server Driver (sqlsrv32.dll) to access databases might not connect. Additionally, you might receive an error in the app, or you might receive an error from the SQL Server. Errors you might receive include the following messages:

  • The EMS System encountered a problem.
    Message: [Microsoft][ODBC SQL Server Driver] Protocol error in TDS Stream.

  • The EMS System encountered a problem.
    Message: [Microsoft][ODBC SQL Server Driver] Unknown token received from SQL Server.

Note for developers: Apps affected by this issue might fail to fetch data, for example when using the SQLFetch function. This issue might occur when calling SQLBindCol function before SQLFetch or calling SQLGetData function after SQLFetch and when a value of 0 (zero) is given for the ‘BufferLength’ argument for fixed datatypes larger than 4 bytes (such as SQL_C_FLOAT).

To decide whether you are using an affected app, open the app which connects to a database. Open a Command Prompt window, type the following command and then press Enter:

tasklist /m sqlsrv32.dll

If the command returns a task, then the app might be affected.

To mitigate this issue, you can do one of the following:

  • If your app is already using or able to use Data Source Name (DSN) to select ODBC connections, install Microsoft ODBC Driver 17 for SQL Server and select it for use with your app using DSN.

    Note: We recommend the latest version of Microsoft ODBC Driver 17 for SQL Server, as it is more compatible with apps currently using the legacy Microsoft ODBC SQL Server Driver (sqlsrv32.dll) than Microsoft ODBC Driver 18 for SQL Server.

  • If your app is unable to use DSN, the app will need to be modified to allow for DSN or to use a newer ODBC driver than Microsoft ODBC SQL Server Driver (sqlsrv32.dll).

This issue was resolved in KB5022352. If you have implemented the above workaround, it is recommended to continue using the configuration in the workaround.
