Palo Alto Networks Cloud NGFW: denial of service
Fix: upgrade to 12.1.4-h8 or later (6 fixed versions below)
Multiple 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.
Panorama is not impacted by these vulnerabilities.
