The remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2020:5363 advisory.
Red Hat OpenShift Container Platform is Red Hat's cloud computing Kubernetes application platform solution designed for on-premise or private cloud deployments.
Security Fix(es):
* kubernetes: compromised node could escalate to cluster level privileges (CVE-2020-8559)
* kubernetes: improper validation of URL redirection in the Kubernetes API server allows an attacker- controlled Kubelet to redirect API server requests from streaming endpoints (CVE-2018-1002102)
For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.
This advisory contains the RPM packages for Red Hat OpenShift Container Platform 3.11.346. See the following advisory for the container images for this release:
https://access.redhat.com/errata/RHBA-2020:5362
All OpenShift Container Platform 3.11 users are advised to upgrade to these updated packages and images.
Tenable has extracted the preceding description block directly from the Red Hat Enterprise 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.
