Hyper-V Information Disclosure Vulnerability - CVE-2019-1230

oval:org.cisecurity:def:6489

An information disclosure vulnerability exists when the Windows Hyper-V Network Switch on a host operating system fails to properly validate input from an authenticated user on a guest operating system. To exploit the vulnerability an attacker on a guest operating system could run a specially crafted application that could cause the Hyper-V host operating system to disclose memory information. An attacker who successfully exploited the vulnerability could gain access to information on the Hyper-V host operating system. The security update addresses the vulnerability by correcting how the Windows Hyper-V Network Switch validates guest operating system user input.
