The vulnerability is due to a logic error in how the software cryptography module handles specific types of decryption errors. An attacker could exploit this vulnerability by sending malicious packets over an established IPsec connection. A successful exploit could cause the device to crash, forcing it to reload. Important: Successful exploitation of this vulnerability would not cause a compromise of any encrypted data. Note: This vulnerability affects only Cisco ASA Software Release 9.16.1 and Cisco FTD Software Release 7.0.0."}, {"lang": "es", "value": "Una vulnerabilidad en el m\u00f3dulo de criptograf\u00eda de software de Cisco Adaptive Security Appliance (ASA) Software y Cisco Firepower Threat Defense (FTD) Software, podr\u00eda permitir a un atacante remoto autenticado o a un atacante no autenticado en una posici\u00f3n de tipo man-in-the-middle causar una recarga inesperada del dispositivo que resulta en una condici\u00f3n de denegaci\u00f3n de servicio (DoS).
