CVE-2017-0021 [CRITICAL] Hyper-V vSMB Remote Code Execution Vulnerability
Hyper-V vSMB Remote Code Execution Vulnerability
Description: A remote code execution vulnerability exists when Windows Hyper-V on a host server fails to properly validate vSMB packet data. An attacker who successfully exploited these vulnerabilities could execute arbitrary code on a target operating system.
To exploit these vulnerabilities, an attacker running inside a virtual machine could run a specially crafted application that could cause the Hyper-V host operating system to execute arbitrary code.
The update addresses the vulnerabilities by correcting how Windows Hyper-V validates vSMB packet data.
