Summary
Denial of service vulnerabilities in Palo Alto Networks PAN-OS® software allow an unauthenticated attacker with network access to cause a denial of service (DoS) condition by sending specially crafted network traffic to or through a dataplane interface. Repeated attempts to trigger this condition result in the firewall entering maintenance mode.
Cloud NGFW and Panorama are not affected by this vulnerability.
