Descriptions
<p>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.</p>
<p>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.</p>
<p>The security update addresses the vulnerability by resolving the conditions where Hyper-V would fail to handle these requests.</p>
Se presenta una vulnerabilidad de denegación de servicio cuando Microsoft Hyper-V en un servidor host presenta un fallo al comprobar apropiadamente datos maliciosos específicos de un usuario en un sistema operativo invitado.
