An attacker could exploit this vulnerability by sending crafted SSH messages to an affected device. A successful exploit could allow the attacker to exhaust available SSH resources on the affected device so that new SSH connections to the device are denied, resulting in a DoS condition. Existing SSH connections to the device would continue to function normally. The device must be rebooted manually to recover. However, user traffic would not be impacted and could be managed using a remote application such as Cisco Adaptive Security Device Manager (ASDM)."}, {"lang": "es", "value": "Una vulnerabilidad en el servidor SSH del software Cisco Adaptive Security Appliance (ASA) podr\u00eda permitir que un atacante remoto no autenticado provoque una condici\u00f3n de denegaci\u00f3n de servicio (DoS) para el servidor SSH de un dispositivo afectado. Esta vulnerabilidad se debe a un error l\u00f3gico cuando se establece una sesi\u00f3n SSH. Un atacante podr\u00eda aprovechar esta vulnerabilidad enviando mensajes SSH manipulados a un dispositivo afectado. Una explotaci\u00f3n exitosa podr\u00eda permitir que el atacante agote los recursos SSH disponibles en el dispositivo afectado para que se denieguen las nuevas conexiones SSH al dispositivo, lo que da como resultado una condici\u00f3n de DoS.
