Synopsis: Critical: OpenShift Container Platform 3.2 security update
Advisory ID: RHSA-2018:3742-01
Product: Red Hat OpenShift Enterprise
Advisory URL: https://access.redhat.com/errata/RHSA-2018:3742
Issue date: 2018-12-03

=====================================================================

1. Summary:

An update is now available for Red Hat OpenShift Container Platform 3.2.

Red Hat Product Security has rated this update as having a security impact
of Critical. A Common Vulnerability Scoring System (CVSS) base score, which
gives a detailed severity rating, is available for each vulnerability from
the CVE link(s) in the References section.

2. Relevant releases/architectures:

Red Hat OpenShift Container Platform 3.2 - noarch, x86_64

3. Description:

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 aservicecataloga 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)

This advisory contains the RPM packages for Red Hat OpenShift Container
Platform 3.2.z. See the following advisory for the container images for
