"The remote Debian 9 host has a package installed that is affected by a vulnerability as referenced in the dla-3038
advisory.

    debian-security-support, the Debian security support coverage checker, has been updated in stretch-
    security to mark the end of life of the following packages: * keystone: See
    https://lists.debian.org/debian-lts/2020/05/msg00011.html for further information. * libspring-java: See
    https://lists.debian.org/debian-lts/2021/12/msg00008.html for further information. * guacamole-client: See
    https://lists.debian.org/debian-lts/2022/01/msg00015.html for further information. * gpac: See
    https://lists.debian.org/debian-lts/2022/04/msg00008.html for further information. * ansible: Lack of an
    effective test suite makes proper support impossible. * mysql-connector-java: Details of security
    vulnerabilities are not disclosed. MySQL has been replaced by MariaDB. We recommend to use mariadb-
    connector-java instead. * ckeditor3: See https://lists.debian.org/debian-lts/2022/05/msg00060.html for
    further information. For Debian 9 stretch, this problem has been fixed in version 1:9+2022.06.02. We
    recommend that you upgrade your debian-security-support packages. For the detailed security status of
    debian-security-support please refer to its security tracker page at: https://security-
    tracker.debian.org/tracker/debian-security-support Further information about Debian LTS security
    advisories, how to apply these updates to your system and frequently asked questions can be found at:
