Vulnerability Information

Windows Graphics Component Information Disclosure Vulnerability - 
CVE-2016-3216

An information disclosure vulnerability exists when the Windows Graphics 
Component (GDI32.dll) fails to properly handle objects in memory, allowing an
attacker to retrieve information that could lead to an Address Space Layout 
Randomization (ASLR) bypass. An attacker who successfully exploited this 
vulnerability could cause an information disclosure to bypass the ASLR 
security feature that protects users from a broad class of vulnerabilities.

The security feature bypass itself does not allow arbitrary code execution. 
However, an attacker could use the ASLR bypass vulnerability in conjunction 
with another vulnerability, such as a remote code execution vulnerability, 
that could take advantage of the ASLR bypass to run arbitrary code.

To exploit this vulnerability, an attacker could convince a use to run a 
specially crafted application. The security update addresses the vulnerability
by correcting how the Windows Graphics Component handles addresses in memory.

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

Vulnerability title 						CVE number 	Publicly disclosed 	Exploited

Windows Graphics Component Information Disclosure Vulnerability CVE-2016-3216 	No 			No

Win32k Elevation of Privilege Vulnerability - CVE-2016-3219

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

In a local attack scenario, an attacker could exploit this vulnerability by 
running a specially crafted application to take control of the affected 
system. The update addresses the vulnerability by correcting how the Windows 
kernel-mode driver handles objects in memory and by helping to prevent 
unintended elevation of privilege from user-mode.

The following table contains 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-2016-3219 	No 			No

ATMFD.dll Elevation of Privilege Vulnerability - CVE-2016-3220

An elevation of privilege vulnerability exists in Adobe Type Manager Font 
Driver (ATMFD.dll) when it fails to properly handle objects in memory. An 
attacker who successfully exploited this vulnerability could execute arbitrary
code and take control of an affected system. An attacker could then install 
programs; view, change, or delete data; or create new accounts with full user
rights.

To exploit the vulnerability, an attacker would first have to log on to a 
target system and then run a specially crafted application. The security 
update addresses the vulnerability by correcting how ATMFD.dll handles objects
in memory.

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

Vulnerability title 				CVE number 	Publicly disclosed 	Exploited

ATMFD.dll Elevation of Privilege Vulnerability 	CVE-2016-3220 	No 			No
