Summary

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 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)
