Synopsis

The remote Red Hat host is missing one or more security updates.

Description

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.

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.

Solution

Update the affected packages.
