Descriptions

A null pointer dereference vulnerability in Palo Alto Networks PAN-OS software enables an unauthenticated attacker to stop a core system service on the firewall by sending a crafted packet through the data plane 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 el software PAN-OS de Palo Alto Networks permite a un atacante no autenticado detener un servicio central del sistema en el firewall mediante el envío de un paquete manipulado a través del plano de datos 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.
