Vulnerability Information

Win32k Elevation of Privilege Vulnerability - CVE-2016-7259

An elevation of privilege vulnerability exists when the Windows Graphics Component improperly handles objects in memory. An attacker who successfully exploited this vulnerability could run processes in an elevated context.

To exploit this vulnerability an attacker could run a specially crafted application to take control of the affected system.

The update addresses the vulnerability by correcting the way in which the Microsoft Graphics Component handles objects in memory and prevent unintended elevation from user-mode.

Win32k Elevation of Privilege Vulnerability - CVE-2016-7260

An elevation of privilege vulnerability exists in Windows when the Windows kernel-mode driver fails to properly handle objects in memory. An attacker who successfully exploited this vulnerability could run arbitrary code in kernel mode. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.

To exploit this vulnerability, an attacker would first have to log on to the system. An attacker could then run a specially crafted application that could exploit the vulnerability and take control of an affected system. The update addresses this vulnerability by correcting how the Windows kernel-mode driver handles objects in memory.

The following table contains links to the standard entry for each vulnerability in the Common Vulnerabilities and Exposures list:
