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

1. Summary:

Red Hat OpenShift Container Platform release 3.7.72 is now available with
updates to packages and images that fix several bugs.

Red Hat Product Security has rated this update as having a security impact
of Important. 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 3.7 - 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.

This advisory contains the RPM packages for Red Hat OpenShift Container
Platform 3.7.72. See the following advisory for the container images for
this release:

https://access.redhat.com/errata/RHBA-2018:2905

Security Fix:

* 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, acknowledgments, 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 this issue.

Bug Fix:

* The etcd v2 to v3 migration playbooks improperly attempted to assign a
TTL of 0 seconds to certain migrated keys when the environment was
previously configured for a 0-second TTL, causing the v2 to v3 migration to
fail. The migration playbooks now assign a 1-second TTL to migrated keys
when those keys had a 0-second TTL configured. This ensures that TTLs are
migrated and those keys will immediately expire after 1s. This effectively
provides a 0-second TTL because this migration process happens while the
API is offline and those keys would expire prior to the API coming back
online. (BZ#1622336)

All OpenShift Container Platform 3.7 users are advised to upgrade to these
updated packages and images.

4. Solution:

Before applying this update, ensure all previously released errata relevant
to your system have been applied.

3.7.72, for important instructions on how to upgrade your cluster and fully
apply this asynchronous errata update:

ease_notes.html

This update is available via the Red Hat Network. Details on how to use the
