Vulnerability Information

Windows Diagnostics Hub Elevation of Privilege Vulnerability - CVE-2016-3231

An elevation of privilege vulnerability exists when the Windows Diagnostics 
Hub Standard Collector Service fails to properly sanitize input, leading to an
unsecure library loading behavior. An attacker who successfully exploited this
vulnerability could run arbitrary code with elevated system privileges. 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 have to log on to an affected
system and run a specially crafted application. The security update addresses
the vulnerability by correcting how the Windows Diagnostics Hub Standard 
Collector Service sanitizes input, to help preclude unintended elevated system
privileges.

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

Vulnerability Title 						CVE number 	Publicly disclosed 	Exploited

Windows Diagnostics Hub Elevation of Privilege Vulnerability 	CVE-2016-3231 	No			No
