PAN-OS: Firewall Denial of Service (DoS) in DNS Security Using a Specially Crafted Packet
Description
A Denial of Service vulnerability in the DNS Security feature of Palo Alto Networks PAN-OS software allows an unauthenticated attacker to send a malicious packet through the data plane of the firewall that reboots the firewall. Repeated attempts to trigger this condition will cause the firewall to enter maintenance mode. This issue is applicable to the PAN-OS software versions listed below on PA-Series firewalls, VM-Series firewalls, CN-Series firewalls, and Prisma Access.
