Windows Agent Activation Runtime Information Disclosure Vulnerability

An information disclosure vulnerability exists when the Windows Agent Activation Runtime (AarSvc) fails to properly handle objects in memory. An attacker who successfully exploited the vulnerability could obtain information to further compromise the user’s system.

To exploit this vulnerability, an attacker would first have to log on to the system. An attacker could then run a specially crafted application.

The update addresses the vulnerability by correcting how the Windows Agent Activation Runtime handles objects in memory.
