Descriptions

The PROFINET (PNIO) stack, when integrated with the Interniche IP stack, improperly handles internal resources for TCP segments where the minimum TCP-Header length is less than defined.

This could allow an attacker to create a denial of service condition for TCP services on affected devices by sending specially crafted TCP segments.

La pila PROFINET (PNIO), cuando se integra con la pila IP de Interniche, maneja incorrectamente los recursos internos para los segmentos TCP en los que la longitud mínima del TCP-Header es inferior a la definida. Esto podría permitir a un atacante crear una condición de denegación de servicio para los servicios TCP en los dispositivos afectados mediante el envío de segmentos TCP especialmente diseñados
