Red Hat Security Advisory: atomic-openshift security and bug fix update
Severity
Important
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).
