Scroller Redhat
Updates rolled out for Kubernetes within Red Hat OpenShift to mitigate moderate security risks. Crucial for enhancing deployment security.
Updated kubernetes packages that fix one security issue are now available for Red Hat OpenShift Enterprise 3.0

Solution

Before applying this update, make sure all previously released errata relevant to your system have been applied.

For details on how to apply this update, refer to:

https://access.redhat.com/articles/11258

Summary

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.
