The remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2018:2908 advisory.

  • atomic-openshift: oc patch with json causes masterapi service crash (CVE-2018-14632)

  • kubernetes: authentication/authorization bypass in the handling of non-101 responses (CVE-2018-1002105)

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