Name of the Vulnerable Software and Affected Versions etcd versions 3.3.0 through 3.3.22 etcd versions 3.4.0 through 3.4.9

Description 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.

Recommendations For etcd versions 3.3.0 through 3.3.22, update to version 3.3.23 or later. For etcd versions 3.4.0 through 3.4.9, update to version 3.4.10 or later. As a temporary workaround, consider restricting access to the etcd gateway to minimize the risk of exploitation.
