ImprovementsThis security update includes improvements that were a part of update KB5014021 (released May 24, 2022) and also addresses the following issues:
If you installed earlier updates, only the new updates contained in this package will be downloaded and installed on your device.
- Addresses an elevation of privilege (EOP) vulnerability under CVE-2022-30154 for the Microsoft File Server Shadow Copy Agent Service. To become protected and functional, you must install the June 14, 2022 or later Windows update on both the application server and the file server. The application server runs the Volume Shadow Copy Service (VSS)-aware application that stores data on the remote Server Message Block 3.0 (or higher) shares on a file server. The file server hosts the file shares. If you don’t install the update on both machine roles, backup operations carried out by applications, which previously worked, might fail. For such failure scenarios, the Microsoft File Server Shadow Copy Agent Service will log FileShareShadowCopyAgent event 1013 on the file server. For more information, see KB5015527.
