Synopsis: Critical: OpenShift Container Platform 3.7 security and bug fix update
Advisory ID: RHSA-2018:1231-01
Product: Red Hat OpenShift Enterprise
Advisory URL: https://access.redhat.com/errata/RHSA-2018:1231
Issue date: 2018-04-29
CVE Names: CVE-2018-1102
=====================================================================

1. Summary:

An update is now available for Red Hat OpenShift Container Platform 3.7.

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 3.7 - noarch, x86_64

3. Description:

Red Hat OpenShift Container Platform is the company's cloud computing
Platform-as-a-Service (PaaS) solution designed for on-premise or private
cloud deployments.

This advisory contains RPM packages for this release. See the following
advisory for the container images for this release:

https://access.redhat.com/errata/RHBA-2018:1230

Security Fix(es):

* source-to-image: Improper path sanitization in
ExtractTarStreamFromTarReader in tar/tar.go (CVE-2018-1102)

This update also fixes the following bugs:

* Fluentd inserts documents (logs) into Elasticsearch using the bulk insert
API, but relies upon Elasticsearch to generate UUIDs for each document. It
does not remove successfully indexed documents from the bulk payload when
the bulk operation fails. This caused the initial payload to be resubmitted
and documents that were successfully indexed to be submitted again, which
results in duplicate documents with different UUIDs. This bug fix ensures
that document IDs are generated before submitting bulk insert requests. As
a result, Elasticsearch will disregard the insertion of documents that
already exist in the data store and insert documents that do not.
(BZ#1556896)

* A user can set a host name to `localhost`, which confuses the router
check to see if the reload completed. This caused the reload to never
return success, causing the router to fail. This bug fix changes the health
check so that it does not pass the host name `localhost`. As a result,
routers can now reload successfully. (BZ#1548102)

For more details about the security issue(s), including the impact, a CVSS
score, acknowledgments, and other related information, refer to the CVE
