Summary
Etcd Gateway can include itself as an endpoint resulting in resource exhaustion
Details

Vulnerability type

Denial of Service

Detail

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.
