Windows Hyper-V Denial of Service Vulnerability - CVE-2018-8437

oval:org.cisecurity:def:5961

A denial of service vulnerability exists when Microsoft Hyper-V Network Switch on a host server fails to properly validate input from a privileged user on a guest operating system. An attacker who successfully exploited the vulnerability could cause the host server to crash. 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 that causes a host machine to crash. The update addresses the vulnerability by modifying how virtual machines access the Hyper-V Network Switch.
