The vulnerability is due to incomplete input validation of a Secure Sockets Layer (SSL) or Transport Layer Security (TLS) ingress packet header. An attacker could exploit this vulnerability by sending a crafted TLS/SSL packet to an interface on the targeted device. An exploit could allow the attacker to cause the device to reload, which will result in a denial of service (DoS) condition. Note: Only traffic directed to the affected system can be used to exploit this vulnerability. This vulnerability affects systems configured in routed and transparent firewall mode and in single or multiple context mode. This vulnerability can be triggered by IPv4 and IPv6 traffic. A valid SSL or TLS session is required to exploit this vulnerability."}, {"lang": "es", "value": "\"Una vulnerabilidad en el controlador criptogr\u00e1fico de los programas Adaptive Security Appliance (ASA) y Firepower Threat Defense (FTD) de Cisco, podr\u00eda permitir a un atacante remoto no identificado provocar que el dispositivo se reinicie inesperadamente. La vulnerabilidad es debido a la validaci\u00f3n de entrada incompleta de un encabezado de paquete de ingreso de Secure Sockets Layer (SSL) o Transport Layer Security (TLS). Un atacante podr\u00eda explotar esta vulnerabilidad mediante el env\u00edo de un paquete TLS/SSL dise\u00f1ado a una interfaz en el dispositivo de destino. Un explotaci\u00f3n podr\u00eda permitir al atacante causar que el dispositivo se recargue, lo que resultar\u00e1 en una condici\u00f3n de denegaci\u00f3n de servicio (DoS). Nota: solo el tr\u00e1fico direccionado al sistema afectado puede ser usado para explotar esta vulnerabilidad. Esta vulnerabilidad afecta a los sistemas configurados en el modo de firewall enrutado y transparente y en modo de contexto \u00fanico o m\u00faltiple.
