MS16-034: Security Update for Windows Kernel-Mode Drivers to Address Elevation of Privilege (3143145)

high Nessus Plugin ID 89756
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

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 flaws in the Win32k kernel-mode driver due to improper handling of objects in memory. An authenticated, remote attacker can exploit these, via a specially crafted application, to elevate privileges, allowing the execution of arbitrary code in kernel mode.

Solution

Microsoft has released a set of patches for Vista, 2008, 7, 2008 R2, 2012, 8.1, RT 8.1, 2012 R2, and 10.
