Scroller Redhat
Canonical has issued a significant security patch for kubernetes-apiservers to mitigate possible denial-of-service vulnerabilities.
An update for openstack-cinder is now available for Red Hat Enterprise Linux OpenStack Platform 5.0 (Icehouse) for RHEL 7

Solution

For details on how to apply this update, which includes the changes described in this advisory, refer to:

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

Summary

OpenStack Block Storage (cinder) manages block storage mounting and the presentation of such mounted block storage to instances. The backend physical storage can consist of local disks, or Fiber Channel, iSCSI, and NFS mounts attached to Compute nodes. In addition, Block Storage supports volume backups, and snapshots for temporary save and restore operations. Programmatic management is available via Block Storage's API.
Security Fix(es):
* A resource vulnerability in the Block Storage (cinder) service was found in its use of qemu-img. An unprivileged user could consume as much as 4 GB of RAM on the compute host by uploading a malicious image. This flaw could lead possibly to host out-of-memory errors and negatively affect other running tenant instances. (CVE-2015-5162)
