Windows AppContainer Elevation Of Privilege Vulnerability

An elevation of privilege vulnerability exists when AppContainer improperly implements constrained impersonation. An attacker who successfully exploited this vulnerability could run processes in an elevated context.

To exploit the vulnerability, an attacker would first have to log on to the system, and then run a specially crafted application to take control over the affected system.

The security update addresses the vulnerability by correcting how AppContainer implements constrained impersonation.
