A remote attacker with SSH access can take advantage of this issue to gain PolicyKit privileges that are normally only granted to clients in an active session on the local console. For the stable distribution (stretch), this problem has been fixed in version 232-25+deb9u11. This update includes updates previously scheduled to be released in the stretch 9.9 point release. We recommend that you upgrade your systemd packages.
