RHSA-2015:1945 - Security Advisory

Topic

Updated kubernetes packages that fix one security issue are now
available for Red Hat OpenShift Enterprise 3.0.

Red Hat Product Security has rated this update as having Moderate
security impact. A Common Vulnerability Scoring System (CVSS) base
score, which gives a detailed severity rating, is available from the
CVE link in the references section.

Description

Kubernetes allows orchestration and control of Docker containers as used in OpenShift Enterprise 3.

Kubernetes fails to validate object name types before passing the data to etcd. As the etcd service generates keys based on the object name type this can lead to a directory path traversal. (CVE-2015-5305)

Red Hat would like to thank Jordan Liggitt for discovering and
reporting this issue.
