Overview

Affected versions of this package are vulnerable to Stack-based Buffer Overflow in the OpenHandler process. An attacker can cause a crash of the SbieSvc service or potentially execute code as SYSTEM by sending a specially crafted message with an unterminated server field to the service pipe from within a sandboxed environment. This is only exploitable if the attacker has the ability to send messages as a sandboxed caller.
