Descriptions

A denial of service vulnerability exists when Microsoft Hyper-V on a host server fails to properly validate specific malicious data from a user on a guest operating system.
To exploit the vulnerability, an attacker who already has a privileged account on a guest operating system, running as a virtual machine, could run a specially crafted application.
The security update addresses the vulnerability by resolving the conditions where Hyper-V would fail to handle these requests.

Se presenta una vulnerabilidad de denegación de servicio cuando Microsoft Hyper-V en un servidor host no comprueba apropiadamente datos maliciosos específicos de un usuario en un sistema operativo invitado. Para explotar la vulnerabilidad, un atacante que ya posee una cuenta privilegiada en un sistema operativo invitado, ejecutándose como una máquina virtual, podría ejecutar una aplicación especialmente diseñada. La actualización de seguridad corrige la vulnerabilidad al resolver las condiciones donde Hyper-V no podría manejar estas peticiones, también se conoce como "Windows Hyper-V Denial of Service Vulnerability". Este ID de CVE es diferente de CVE-2020-0890
