The vulnerability is due to improper handling of an HTTP packet stream. An attacker could exploit this vulnerability by sending a crafted HTTP packet stream to the detection engine on the targeted device. An exploit could allow the attacker to cause a DoS condition if the Snort process restarts and traffic inspection is bypassed or traffic is dropped."}, {"lang": "es", "value": "Una vulnerabilidad en el reensamblaje del motor de detecci\u00f3n de paquetes HTTP para Cisco Firepower System Software en versiones anteriores a 6.0.1 podr\u00eda permitir a un atacante remoto no autenticado provocar una condici\u00f3n de denegaci\u00f3n de servicio (DoS) debido al reinicio inesperado del proceso Snort.
