Node.js before 10.24.0, 12.21.0, 14.16.0, and 15.10.0 is vulnerable to a denial of service attack when too many connection attempts with an 'unknownProtocol' are established. This leads to a leak of file descriptors. If a file descriptor limit is configured on the system, then the server is unable to accept new connections and prevent the process also from opening, e.g. a file. If no file descriptor limit is configured, then this lead to an excessive memory usage and cause the system to run out of memory.

Node.js versiones anteriores a 10.24.0, 12.21.0, 14.16.0 y 15.10.0, es vulnerable a un ataque de denegación de servicio cuando son establecidos demasiados intentos de conexión con un "unknownProtocol". Esto conlleva a una filtración de descriptores de archivos. Si es configurado un límite de descriptor de archivo en el sistema, entonces el servidor no puede aceptar nuevas conexiones e impide que el proceso también se abra, por ejemplo, un archivo. Si no es configurado ningún límite de descriptor de archivo, esto conllevará a un uso excesivo de la memoria y causará al sistema quedarse sin memoria
