MS11-012: Vulnerabilities in Windows Kernel-Mode Drivers Could Allow Elevation of Privilege (2479628)

high Nessus Plugin ID 51912
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 Windows kernel is affected by multiple vulnerabilities.

Description

The remote host is running a version of the Windows kernel that is affected by one or more of the following vulnerabilities :

- The Win32k.sys kernel-mode driver improperly validates data supplied from user mode to kernel mode.
(CVE-2011-0086)

- The Win32k.sys kernel-mode driver insufficiently validates data supplied from user mode to kernel mode.
(CVE-2011-0087)

- The Win32k.sys kernel-mode driver does not properly validate data supplied from user mode to kernel mode, resulting in a 'Window Class Pointer Confusion' vulnerability. (CVE-2011-0088)

- The Win32k.sys kernel-mode driver does not properly validate data supplied from user mode to kernel mode, resulting in a 'Window Class Improper Pointer Validation' vulnerability. (CVE-2011-0089)

- The Win32k.sys kernel-mode driver does not properly validate data supplied from user mode to kernel mode, resulting in a memory corruption vulnerability.
(CVE-2011-0090)

An attacker with local access to the affected system can exploit these issues to execute arbitrary code in kernel mode and take complete control of the affected system.

Solution

Microsoft has released a set of patches for Windows XP, 2003, Vista, 2008, 7, and 2008 R2.
