The remote Oracle Linux 9 host has a package installed that is affected by multiple vulnerabilities as referenced in the ELSA-2024-2170 advisory.
- Fix for CVE-2023-6377, CVE-2023-6478
Tenable has extracted the preceding description block directly from the Oracle Linux security advisory.
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
