Microsoft has released extraordinary emergency patches for Windows that have fixed a bug that could cause problems with logging into Azure Active Directory and Microsoft 365 on ARM devices (after installing the June updates).
Let me remind you that we also wrote that New Phishing Campaign Targets Microsoft Office 365 Credentials, as well as that For security reasons, Microsoft disabled macros in Excel 4.0 (XLM).Emergency patches will be automatically distributed via Windows Update, and can also be downloaded and installed manually via the Microsoft Update Catalog (KB5016139 for Windows 10 and KB5016138 for Windows 11).
The full list of Windows versions affected by this issue is: Windows 11 21H2, Windows 10 21H2, Windows 10 21H1 and Windows 10 20H2.
According to a warning issued to Microsoft 365 customers, the bug can manifest itself in a variety of scenarios, including apps and services that use Azure Active Directory (Azure AD) for sign-in, VPN connections, Microsoft Teams desktop, OneDrive for Business, Outlook desktop client.
If for some reason users cannot install the latest patches right now, a workaround is available for them: in this case, the company recommends temporarily switching to the web version of the products.
Bleeping Computer notes that the June updates provoked many other problems in Microsoft products, including:
- connection problems while using Wi-Fi hotspots;
- VPN and RDP connectivity issues on servers with Routing and Remote Access Service (RRAS) enabled.
- Windows Server backup issues if applications fail to back up using the Volume Shadow Copy Service (VSS).
