CVE-2019-0965
Plain English Summary
AI-powered analysis for quick understanding
An attacker can run malicious code on the main server hosting Hyper-V by tricking it through a specially crafted application on a guest operating system. This requires the attacker to have access to that guest operating system, making it crucial for organizations to secure their virtual environments.
Technical Description
A remote code execution vulnerability exists when Windows Hyper-V on a host server fails to properly validate input from an authenticated user on a guest operating system. To exploit the vulnerability, an attacker could run a specially crafted application on a guest operating system that could cause the Hyper-V host operating system to execute arbitrary code. An attacker who successfully exploited the vulnerability could execute arbitrary code on the host operating system. The security update addresses the vulnerability by correcting how Hyper-V validates guest operating system user input.
