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 ectd before versions 3.4.10 and 3.3.23, gateway TLS authentication is only applied to endpoints detected in DNS SRV records. When starting a gateway, TLS authentication will only be attempted on endpoints identified in DNS SRV records for a given domain, which occurs in the discoverEndpoints function. No authentication is performed against endpoints provided in the --endpoints flag. This has been fixed in versions 3.4.10 and 3.3.23 with improved documentation and deprecation of the functionality.
