Descriptions

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

Una vulnerabilidad de desreferencia de puntero nulo en la puerta de enlace GlobalProtect del software PAN-OS de Palo Alto Networks permite que un atacante no autenticado detenga el servicio GlobalProtect en el firewall mediante el envío de un paquete especialmente manipulado que provoca una condición de denegación de servicio (DoS). Los intentos repetidos de activar esta condición hacen que el firewall entre en modo de mantenimiento.
