Etcd Gateway can include itself as an endpoint resulting in resource exhaustion
Packages
| Ecosystem | Package | Affected | Fixed in |
|---|---|---|---|
| Go | go.etcd.io/etcd | >= 3.4.0-rc.0, < 3.4.10 | 3.4.10 |

Details
As written in the advisory (Markdown source, shown as plain text).
### 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.
