      "value": "An improper handling of exceptional conditions vulnerability exists in the DNS proxy feature of Palo Alto Networks PAN-OS software that enables a meddler-in-the-middle (MITM) to send specifically crafted traffic to the firewall that causes the service to restart unexpectedly. Repeated attempts to send this request result in denial-of-service to all PAN-OS services by restarting the device in maintenance mode. This issue does not impact Panorama appliances and Prisma Access customers. This issue impacts: PAN-OS 8.1 versions earlier than PAN-OS 8.1.22; PAN-OS 9.0 versions earlier than PAN-OS 9.0.16; PAN-OS 9.1 versions earlier than PAN-OS 9.1.13; PAN-OS 10.0 versions earlier than PAN-OS 10.0.10; PAN-OS 10.1 versions earlier than PAN-OS 10.1.5. This issue does not impact PAN-OS 10.2."

      "value": "Se presenta una vulnerabilidad de manejo inapropiado de condiciones excepcionales en la funci\u00f3n de proxy DNS del software PAN-OS de Palo Alto Networks que permite a un atacante de tipo meddler-in-the-middle (MITM) enviar tr\u00e1fico espec\u00edficamente dise\u00f1ado al firewall que causa un reinicio no esperado del servicio. Los intentos repetidos de enviar esta petici\u00f3n resultan en una denegaci\u00f3n de servicio a todos los servicios de PAN-OS, reiniciando el dispositivo en modo de mantenimiento. Este problema no afecta a dispositivos de Panorama ni a clientes de Prisma Access. Este problema afecta a: PAN-OS versiones anteriores a 8.1.22; PAN-OS 9.0 versiones anteriores a PAN-OS 9.0.16; PAN-OS 9.1 versiones anteriores a PAN-OS 9.1.13; PAN-OS 10.0 versiones anteriores a PAN-OS 10.0.10; PAN-OS 10.1 versiones anteriores a PAN-OS 10.1.5.
