RHEL 7 : OpenShift Container Platform 3.7 (RHSA-2018:2906)

critical Nessus Plugin ID 119406

Language:

Synopsis

The remote Red Hat host is missing one or more security updates for OpenShift Container Platform 3.7.

Description

The remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2018:2906 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):

* A privilege escalation vulnerability exists in OpenShift Container Platform 3.x which allows for compromise of pods running on a compute node to which a pod is scheduled with normal user privilege. This access could include access to all secrets, pods, environment variables, running pod/container processes, and persistent volumes, including in privileged containers. Additionally, on versions 3.6 and higher of OpenShift Container Platform, this vulnerability allows cluster-admin level access to any API hosted by an aggregated API server. This includes the servicecatalog API which is installed by default in 3.7 and later. Cluster-admin level access to the service catalog allows creation of brokered services by an unauthenticated user with escalated privileges in any namespace and on any node. This could lead to an attacker being allowed to deploy malicious code, or alter existing services. (CVE-2018-1002105)

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

For more details about the security issue(s), including the impact, a CVSS score, and other related information, refer to the CVE page(s) listed in the References section.

Red Hat would like to thank Lars Haugan for reporting CVE-2018-14632.

Space precludes documenting all of the bug fixes and enhancements in this advisory. See the following Release Notes documentation for details about these changes:

https://docs.openshift.com/container-platform/3.7/release_notes/ocp_3_7_release_notes.html

All OpenShift Container Platform 3.7 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.

Solution

Update the RHEL OpenShift Container Platform 3.7 package based on the guidance in RHSA-2018:2906.
