affected system and runs a specially crafted application.
This security update is rated Important for all supported editions of
Microsoft Windows 10.
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
