The remote Redhat Enterprise Linux 7 / 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2021:1551 advisory.
golang: math/big: panic during recursive division of very large numbers (CVE-2020-28362)
jenkins: lack of type validation in agent related REST API (CVE-2021-21639)
jenkins: view name validation bypass (CVE-2021-21640)
jetty: Symlink directory exposes webapp directory contents (CVE-2021-28163)
jetty: Resource exhaustion when receiving an invalid large TLS frame (CVE-2021-28165)
golang: crypto/elliptic: incorrect operations on the P-224 curve (CVE-2021-3114)
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
