"An update is now available for Red Hat OpenShift Enterprise 3.1 and
Red Hat OpenShift Enterprise 3.2.

Red Hat Product Security has rated this update as having a security
impact of Moderate. 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.

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

The logging auth proxy is a reverse proxy that authenticates requests
against OpenShift, retrieving user information and setting the
configured header with the appropriate details.

Security Fix(es) :

* A regular expression denial of service flaw was found in Negotiator.
An attacker able to make an application using Negotiator to perform
matching using a specially crafted glob pattern could cause the
application to consume an excessive amount of CPU. (CVE-2016-1000022)

* A regular expression denial of service flaw was found in Minimatch.
An attacker able to make an application using Minimatch to perform
matching using a specially crafted glob pattern could cause the
application to consume an excessive amount of CPU. (CVE-2016-1000023)

Refer to the changelog listed in the References section for a list of
changes.

This update includes the following images :

openshift3/logging-auth-proxy:3.1.1-13
openshift3/logging-auth-proxy:3.2.1-5

All OpenShift Enterprise 3 users are advised to upgrade to the updated
images."
