Microsoft Windows/Windows Server Denial of Service Vulnerability (CNVD-2021-66067)

Microsoft Windows and Microsoft Windows Server are both products of Microsoft Corporation, an operating system for personal devices, and Microsoft Windows Server, a server operating system. A denial of service vulnerability exists in Microsoft Windows/Windows Server. The vulnerability stems from the failure of Microsoft Hyper-V on the host server to properly authenticate specific malicious data from users of the client operating system, and can be exploited by attackers running specially crafted applications to cause a denial of service.
