An attacker could exploit this vulnerability by sending crafted SSL packets through an established connection to be parsed by the Snort 3 Detection Engine. A successful exploit could allow the attacker to cause a denial of service (DoS) condition when the Snort 3 Detection Engine unexpectedly restarts."},{"lang":"es","value":"Una vulnerabilidad en el manejo de la gestión de memoria para el Motor de Detección Snort 3 del software Cisco Secure Cortafuegos Defensa contra Amenazas (FTD) podría permitir a un atacante remoto no autenticado causar que el Motor de Detección Snort 3 se reinicie.\n\nEsta vulnerabilidad se debe a un error de lógica en la gestión de memoria cuando un dispositivo está realizando inspección de paquetes SSL de Snort 3.
