An issue was discovered in the kernel in NetBSD 7.1. An Access Point (AP)
forwards EAPOL frames to other clients even though the sender has not yet
successfully authenticated to the AP. This might be abused in projected
Wi-Fi networks to launch denial-of-service attacks against connected
clients and makes it easier to exploit other vulnerabilities in connected
clients.
