CVE-2020-15114: Uncontrolled Resource Consumption

August 6, 2020 (updated November 18, 2021)

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.
