MS11-011: Vulnerabilities in Windows Kernel Could Allow Elevation of Privilege (2393802)

high Nessus Plugin ID 51911
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 Windows kernel is affected by several vulnerabilities that could allow escalation of privileges.

Description

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

- A buffer overflow in the 'GreEnableEUDC()' function can be triggered using specially crafted end-user-defined characters (EUDC) registry key values. (CVE-2010-4398)

- An integer truncation vulnerability exists due to the failure of the Windows kernel to validate user-supplied data before allocating memory. (CVE-2011-0045)

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.
