Descriptions
In etcd before versions 3.3.23 and 3.4.10, the etcd gateway is a simple TCP proxy to allow for basic service discovery and access. However, it is possible to include the gateway address as an endpoint. This results in a denial of service, since the endpoint can become stuck in a loop of requesting itself until there are no more available file descriptors to accept connections on the gateway.

Sin embargo, es posible incluir la dirección de la puerta de enlace como endpoint. Esto resulta en una denegación de servicio, ya que el endpoint puede quedarse atrapado en un bucle de petición hasta que no haya más descriptores de archivo disponibles para aceptar conexiones en la puerta de enlace
