Overview

Affected versions of this package are vulnerable to Use After Free in the async message proxy when handling RAIL WINDOW_STATE_ORDER and NOTIFY_ICON_STATE_ORDER with AsyncUpdate enabled. An attacker can cause memory corruption or crash the client by sending crafted update orders from a malicious or compromised RDP server, which results in stale pointers being dispatched after the original buffers have been freed.
