The vulnerability exists because the affected software improperly manages system memory resources when inspecting traffic. An attacker could exploit this vulnerability by generating specific traffic patterns for the software to inspect. A successful exploit could allow the attacker to exhaust system memory resources used for traffic inspection. Depending on the configuration, the FTD Software could fail open and cease to inspect traffic or fail closed and result in a DoS condition. This vulnerability may require manual intervention to restore the software."}, {"lang": "es", "value": "Una vulnerabilidad en el componente de adquisici\u00f3n de datos (DAQ) de Cisco Firepower Threat Defense (FTD) Software podr\u00eda permitir a un atacante remoto no autenticado omitir las pol\u00edticas de control de acceso configuradas o provocar una condici\u00f3n de denegaci\u00f3n de servicio (DoS). Esta vulnerabilidad existe porque el software afectado gestiona incorrectamente los recursos de la memoria del sistema al inspeccionar tr\u00e1fico. Un atacante podr\u00eda explotar esta vulnerabilidad generando patrones de tr\u00e1fico espec\u00edficos para que el software los inspeccione.
