Vulnerability Information Multiple Win32k Elevation of Privilege Vulnerabilities Elevation of privilege vulnerabilities exist when the Windows kernel-mode driver fails to properly handle objects in memory. An attacker who successfully exploited the vulnerabilities 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 the vulnerabilities, an attacker would first have to log on to the system. An attacker could then run a specially crafted application that could exploit the vulnerabilities and take control of an affected system. The update addresses the vulnerabilities by correcting how the Windows kernel-mode driver handles objects in memory. The following tables contain links to the standard entry for each vulnerability in the Common Vulnerabilities and Exposures list: Vulnerability title CVE number Publicly disclosed Exploited Win32k Elevation of Privilege Vulnerability CVE-2016-0143 No No Win32k Elevation of Privilege Vulnerability CVE-2016-0165 No Yes Win32k Elevation of Privilege Vulnerability CVE-2016-0167 No Yes Graphics Memory Corruption Vulnerability CVE-2016-0145 A remote code execution vulnerability exists when the Windows font library improperly handles specially crafted embedded fonts. An attacker who successfully exploited the vulnerability could install programs; view, change, or delete data; or create new accounts with full user rights. There are multiple ways an attacker could exploit the vulnerability, such as by convincing a user to open a specially crafted document, or by convincing a user to visit an untrusted webpage that contains embedded fonts. The security update addresses the vulnerability by correcting how the Windows font library handles embedded fonts.
