MS16-072: Description of the security update for Group Policy: June 14, 2016

Summary

This security update resolves a vulnerability in Microsoft Windows. The vulnerability could allow elevation of privilege if an attacker launches a man-in-the-middle (MiTM) attack against the traffic passing between a domain controller and the target machine.

To learn more about the vulnerability, see Microsoft Security Bulletin MS16-072.

More Information

Important

• All future security and non-security updates for Windows RT 8.1, Windows 8.1, and Windows Server 2012 R2 require update 2919355 to be installed. We recommend that you install update 2919355 on your Windows RT 8.1-based, Windows 8.1-based, or Windows Server 2012 R2-based computer so that you receive future updates.
• If you install a language pack after you install this update, you must reinstall this update. Therefore, we recommend that you install any language packs that you need before you install this update. For more information, see Add language packs to Windows.

Known issues

MS16-072 changes the security context with which user group policies are retrieved. This by-design behavior change protects customers’ computers from a security vulnerability. Before MS16-072 is installed, user group policies were retrieved by using the user’s security context. After MS16-072 is installed, user group policies are retrieved by using the computer’s security context. This issue is applicable for the following KB articles:

• 3159398 MS16-072: Description of the security update for Group Policy: June 14, 2016
• 3163017 Cumulative update for Windows 10: June 14, 2016

Symptoms

All user Group Policy, including those that have been security filtered on user accounts or security groups, or both, may fail to apply on domain joined computers.

Cause

This issue may occur if the Group Policy Object is missing the Read permissions for the Authenticated Users group or if you are using security filtering and are missing Read permissions for the domain computers group.

Resolution

To resolve this issue, use the Group Policy Management Console (GPMC.MSC) and follow one of the following steps:

• Add the Authenticated Users group with Read Permissions on the Group Policy Object (GPO).
• If you are using security filtering, add the Domain Computers group with read permission.
