CVE-2018-0961 [HIGH] 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.
Windows Hyper-V: Windows Hyper-V
Impact: Remote Code Execution

[HIGH] May 2018 Patch Tuesday – Medium Weight, However One Active Exploit Needs Attention
This May’s Patch Tuesday has quite a few Microsoft fixes for both the OS and browsers. In all, 67 unique CVEs are addressed in 17 KB articles, with 21 CVEs marked Critical. 32 of these CVEs reference Remote Code Execution, 19 of which are Critical. Those who use Hyper-V have some updates to pay attention to as well.
## OS, Browser and Office
In terms of prioritization, we recommend patching user-facing assets first, with a focus on OS, browser patches, and Office to resolve scripting engine vulnerabilities.
We recommend you first test and deploy the fixes for CVE-2018-8174 , which addresses how the scripting engine handles memory objects. It should be noted that Microsoft lists this patch as Exploitation Detected, so this update should get immediate attention.
