The Microsoft July security updates have been released and consist of 123 CVEs. Of these 123 CVEs, 18 are rated Critical and 105 are rated Important in severity. None are listed as being under attack at the time of release.
The Windows 10 Release Notes include the following new information:
1. IMPORTANT Starting in July 2020, we will resume non-security releases for Windows 10 and Windows Server, version 1809 and later. There is no change to the cumulative monthly security updates (also referred to as the "B" release or Update Tuesday release). For more information, see the blog post Resuming optional Windows 10 and Windows Server non-security monthly updates.
2. IMPORTANT Starting in July 2020, all Windows Updates will disable the RemoteFX vGPU feature because of a security vulnerability. For more information about the vulnerability, see CVE-2020-1036 and KB4570006. Once this feature is disabled, attempts to start virtual machines (VMs) will fail, and messages such as the following will appear:
- “The virtual machine cannot be started because all the RemoteFX-capable GPUs are disabled in Hyper-V Manager.”
- “The virtual machine cannot be started because the server has insufficient GPU resources.”
If you re-enable RemoteFX vGPU, a message similar to the following will appear:
- "We no longer support the RemoteFX 3D video adapter. If you are still using this adapter, you may become vulnerable to security risk.Learn more (Update to disable and remove the RemoteFX vGPU component in Windows)”
The updates apply to the following: Microsoft Windows, Microsoft Edge (EdgeHTML-based), Microsoft Edge (Chromium-based) in IE Mode, Microsoft ChakraCore, Internet Explorer, Microsoft Office and Microsoft Office Services and Web Apps, Windows Defender, Skype for Business, Visual Studio, Microsoft OneDrive, Open Source Software, .NET Framework and Azure DevOps.
