MS15-051: Vulnerabilities in Windows Kernel-Mode Drivers Could Allow Elevation of Privilege (3057191)

high Nessus Plugin ID 83370
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.


The remote Windows host is affected by multiple vulnerabilities.


The version of Windows running on the remote host is affected by multiple vulnerabilities :

- Multiple information disclosure vulnerabilities exist due to the Win32k.sys kernel-mode driver improperly handling objects in memory. A local attacker can exploit this to reveal private address information during a function call, resulting in the disclosure of kernel memory contents. (CVE-2015-1676, CVE-2015-1677, CVE-2015-1678, CVE-2015-1679, CVE-2015-1680)

- A privilege escalation vulnerability exists due to the Win32k.sys kernel-mode driver improperly handling objects in memory. A local attacker can exploit this flaw, via a specially crafted application, to execute arbitrary code in kernel mode. This vulnerability is reportedly being exploited in the wild. (CVE-2015-1701)


Microsoft has released a set of patches for Windows 2003, Vista, 2008, 7, 2008 R2, 8, 2012, 8.1, and 2012 R2.
