The remote Red Hat Enterprise Linux CoreOS 4 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2021:4829 advisory.

  - coreos-installer: restrict access permissions on /boot/ignition{,/config.ign} (CVE-2021-3917)

  - jenkins: FilePath#mkdirs does not check permission to create parent directories (CVE-2021-21685)

  - jenkins: File path filters do not canonicalize paths, allowing operations to follow symbolic links to     outside allowed directories (CVE-2021-21686)

  - jenkins: FilePath#untar does not check permission to create symbolic links when unarchiving a symbolic     link (CVE-2021-21687)

  - jenkins: FilePath#reading(FileVisitor) does not reject any operations allowing users to have unrestricted     read access (CVE-2021-21688)

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