MS16-045: Security Update for Windows Hyper-V (3143118)

critical Nessus Plugin ID 90438

Synopsis

The remote host is affected by multiple vulnerabilities.

Description

The remote Windows host is missing a security update. It is, therefore, affected by multiple vulnerabilities :

- An arbitrary code execution vulnerability exists in Hyper-V due to a failure to properly validate input from an authenticated user on a guest operating system. An attacker can exploit this, via a crafted application on the guest operating system, to execute arbitrary code on the host operating system. (CVE-2016-0088)

- Multiple information disclosure vulnerabilities exists in Hyper-V due to a failure to properly validate input from an authenticated user on a guest operating system.
An attacker can exploit this, via a crafted application on the guest operating system, to disclose memory information on the host operating system.
(CVE-2016-0089, CVE-2016-0090)

Note that users who have not enabled the Hyper-V role are not affected by these vulnerabilities.

Solution

Microsoft has released a set of patches for Windows 2012, 8.1, 2012 R2, and 10.
