The vulnerability is due to a failure to free system memory when an unexpected DHCP request is received. An attacker could exploit this vulnerability by sending a crafted DHCP packet to the targeted device. A successful exploit could allow the attacker to cause an unexpected reload of the device."},{"lang":"es","value":"Una vulnerabilidad en las interacciones entre las funciones DHCP y TFTP para Cisco Small Business 300 Series (Sx300) Managed Switches, podría permitir que un atacante remoto no autenticado cause que el dispositivo tenga una disminución sobre la memoria del sistema, que a su vez podría generar una recarga inesperada de el dispositivo resultando en una condición de denegación de servicio (DoS) en el dispositivo afectado. La vulnerabilidad se debe a un error al liberar la memoria del sistema cuando una solicitud DHCP inesperada es recibida. Un atacante podría aprovechar esta vulnerabilidad enviando un paquete DHCP creado para el dispositivo de destino. Un aprovechamiento exitoso podría permitir al atacante provocar una recarga inesperada del
