Description		A vulnerability in the TLS processing feature of Cisco Firepower Threat Defense (FTD) Software for Cisco Firepower 2100 Series could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. This vulnerability is due to an issue that occurs when TLS traffic is processed. An attacker could exploit this vulnerability by sending certain TLS traffic over IPv4 through an affected device. A successful exploit could allow the attacker to cause the device to reload, resulting in a DoS condition and impacting traffic to and through the affected device.

value : Una vulnerabilidad en la función de procesamiento de TLS del software Cisco Firepower Threat Defense (FTD) para la serie Cisco Firepower 2100 podría permitir que un atacante remoto no autenticado provoque una condición de denegación de servicio (DoS) en un dispositivo afectado. Esta vulnerabilidad se debe a un problema que ocurre cuando se procesa el tráfico TLS. Un atacante podría aprovechar esta vulnerabilidad enviando cierto tráfico TLS a través de IPv4 a través de un dispositivo afectado. Una explotación exitosa podría permitir que el atacante haga que el dispositivo se recargue, lo que genera una condición de DoS y afecta el tráfico hacia y a través del dispositivo afectado.
