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.
