The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the 4e82a0e6-6801-42c6-8fb6-91b6b275a9e1 advisory.

    The GStreamer project reports:
    Multiple security issues were identified and fixed in the GStreamer framework.

Tenable has extracted the preceding description block directly from the FreeBSD security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The remote Debian 13 host has a package installed that is affected by a vulnerability as referenced in the dsa-6353 advisory.
