A null pointer dereference vulnerability in Palo Alto Networks PAN-OS software enables an unauthenticated attacker to stop a core system service on the firewall by sending a crafted packet through the data plane that causes a denial of service (DoS) condition. Repeated attempts to trigger this condition result in the firewall entering maintenance mode.
