Tuesday, August 11, 2020, Microsoft rolled out is latest batch of security updates. The company states on its website that this release includes improvements and fixes that were a part of the July 2020 release and addresses the following issues:

  • Addresses an issue that prevents you from installing some .msi apps. This occurs when a device is managed by a Group Policy that redirects the AppData folder to a network folder.

  • Addresses an issue in Universal Windows Platform (UWP) apps that allows single sign-on authentication when an app does not have the Enterprise Authentication capability. With the release of CVE-2020-1509, UWP applications might begin prompting the user for credentials.

  • Addresses an issue in Microsoft Edge IE Mode when opening multiple documents from a SharePoint site.

  • Addresses an issue in Microsoft Edge IE Mode that occurs when you browse using anchor links.

  • Addresses an issue with loading Browser Helper Objects in Microsoft Edge IE Mode.

  • Addresses an issue where certain applications that rely on the JScript Scripting Engine become unresponsive under load.

  • Security updates to Windows App Platform and Frameworks, Windows Graphics, Windows Media, Windows Shell, Windows Cloud Infrastructure, Windows Authentication, Windows Kernel, Windows Hybrid Cloud Networking, Windows Peripherals, Windows Network Security and Containers, Windows Storage and Filesystems, Windows File Server and Clustering, Windows Hybrid Storage Services, Windows SQL components, Microsoft Scripting Engine, and Windows Remote Desktop.

 

There is also a known issue in the August 2020 update. The symptom is “certain operations, such as rename, that you perform on files or folders that are on a Cluster Shared Volume (CSV) may fail with the error, ‘STATUS_BAD_IMPERSONATION_LEVEL (0C00000A5)’. This occurs when you perform the operation on a CSV owner node from a process that doesn’t have administrator privilege.

 

Microsoft has provided a workaround for the issue which includes doing either of the following:

 

  • Perform the operation from a process that has administrator privilege

  • Perform the operation from a node that doesn’t have CSV ownership


Microsoft is currently working on a resolution and will provide an update in an upcoming release.
