Summary
Red Hat Security Advisory: atomic-openshift security and bug fix update

Notes

Topic
An update for atomic-openshift is now available for Red Hat OpenShift Enterprise 3.2. 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.
Details
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. Security Fix(es): * The Kubernetes API server contains a watch cache that speeds up performance. Due to an input validation error OpenShift Enterprise may return data for other users and projects when queried by a user. An attacker with knowledge of other project names could use this vulnerability to view their information. (CVE-2016-5392) This issue was discovered by Yanping Zhang (Red Hat). This updates includes the following images: openshift3/openvswitch:v3.2.1.7-1 openshift3/ose-pod:v3.2.1.7-1 openshift3/ose:v3.2.1.7-1 openshift3/ose-docker-registry:v3.2.1.7-1 openshift3/ose-keepalived-ipfailover:v3.2.1.7-1 openshift3/ose-recycler:v3.2.1.7-1 openshift3/ose-f5-router:v3.2.1.7-1 openshift3/ose-deployer:v3.2.1.7-1 openshift3/node:v3.2.1.7-1 openshift3/ose-sti-builder:v3.2.1.7-1 openshift3/ose-docker-builder:v3.2.1.7-1 openshift3/ose-haproxy-router:v3.2.1.7-1 All OpenShift Enterprise 3 users are advised to upgrade to these updated packages and images.
