To exploit this vulnerability, the attacker must have the OSPF secret key.\r\n\r This vulnerability is due to heap corruption in OSPF when parsing packets. An attacker could exploit this vulnerability by sending crafted packets to the OSPF service. A successful exploit could allow the attacker to corrupt the heap, causing the affected device to reload, resulting in a DoS condition."},{"lang":"es","value":"Una vulnerabilidad en el protocolo OSPF de Cisco Secure Firewall ASA Software y Cisco Secure FTD Software podría permitir a un atacante autenticado y adyacente provocar que un dispositivo afectado se recargue inesperadamente, lo que resultaría en una condición de DoS. Para explotar esta vulnerabilidad, el atacante debe tener la clave secreta de OSPF. Esta vulnerabilidad se debe a una corrupción de pila en OSPF al analizar paquetes. Un atacante podría explotar esta vulnerabilidad enviando paquetes manipulados al servicio OSPF.
