CVE-2020-15114 Open this link in a new tabHow to fix?
Upgrade Debian:unstable etcd to version 3.3.25+dfsg-5 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream etcd package and not the etcd package as distributed by Debian.
See How to fix? for Debian:unstable relevant fixed versions and status.
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.
