Descripción es
Una vulnerabilidad en el controlador SSL/TLS del software Cisco Adaptive Security Appliance (ASA) podría permitir que un atacante remoto no autenticado haga que el dispositivo afectado se recargue inesperadamente, lo que genera una condición de denegación de servicio (DoS). La vulnerabilidad se debe a un manejo inadecuado de errores en conexiones SSL/TLS establecidas. Un atacante podría aprovechar esta vulnerabilidad estableciendo una conexión SSL/TLS con el dispositivo afectado y luego enviando un mensaje SSL/TLS malicioso dentro de esa conexión. Una explotación exitosa podría permitir que el atacante haga que el dispositivo se recargue. Cisco ha publicado actualizaciones de software que solucionan esta vulnerabilidad. No existen workarounds que solucionen esta vulnerabilidad.
