      "value": "A vulnerability in the TCP proxy functionality of Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to trigger a denial of service (DoS) condition. This vulnerability is due to improper handling of TCP flows. An attacker could exploit this vulnerability by sending a crafted stream of TCP traffic through an affected device. A successful exploit could allow the attacker to cause the device to reload, resulting in a DoS condition."

Esta vulnerabilidad es debido a un manejo inapropiado de los flujos TCP. Un atacante podr\u00eda explotar esta vulnerabilidad  mediante el env\u00edo de un flujo dise\u00f1ado de tr\u00e1fico TCP a trav\u00e9s de un dispositivo afectado.
