Descriptions
A vulnerability in the SSL/TLS client of Cisco Adaptive Security Appliance (ASA) Software and Cisco Firepower Threat Defense (FTD) Software could allow an authenticated, remote attacker to cause a denial of service (DoS) condition on an affected device.
This vulnerability is due to improper memory management when a device initiates SSL/TLS connections. An attacker could exploit this vulnerability by ensuring that the device will connect to an SSL/TLS server that is using specific encryption parameters. A successful exploit could allow the attacker to cause the affected device to unexpectedly reload, resulting in a DoS condition.
Una vulnerabilidad en el cliente SSL/TLS del software Cisco Adaptive Security Appliance (ASA) y el software Cisco Firepower Threat Defense (FTD) podría permitir que un atacante remoto autenticado cause una condición de Denegación de Servicio (DoS) en un dispositivo afectado. Esta vulnerabilidad se debe a una gestión inadecuada de la memoria cuando un dispositivo inicia conexiones SSL/TLS. Un atacante podría aprovechar esta vulnerabilidad asegurándose de que el dispositivo se conecte a un servidor SSL/TLS que utilice parámetros de cifrado específicos. Un exploit exitoso podría permitir al atacante hacer que el dispositivo afectado entre en bucle de carga inesperadamente, lo que resultaría en una condición DoS.
