Summary: An update for openstack-nova, openstack-cinder, openstack-glance, and python-oslo-concurrency is now available for Red Hat Enterprise Linux OpenStack Platform 7.0 (Kilo) for RHEL 7. Red Hat Product Security has rated this update as having a security impact of Moderate. 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. 2. Relevant releases/architectures: Red Hat Enterprise Linux OpenStack Platform 7.0 (Kilo) for RHEL 7 - noarch 3. Description: The Oslo concurrency library has utilities for safely running multi-thread, multi-process applications using locking mechanisms, and for running external processes. OpenStack Compute (nova) launches and schedules large networks of virtual machines, creating a redundant and scalable cloud computing platform. Compute provides the software, control panels, and APIs required to orchestrate a cloud, including running virtual machine instances and controlling access through users and projects. OpenStack Image Service (glance) provides discovery, registration, and delivery services for disk and server images. The service provides the ability to copy or snapshot a server image, and immediately store it away. Stored images can be used as a template to get new servers up and running quickly and more consistently than installing a server operating system and individually configuring additional services. 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 OpenStack Compute (nova), Block Storage (cinder), and Image (glance) services was found in their 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. oslo.concurrency has been updated to support process limits ('prlimit'), which is needed to fix this flaw. (CVE-2015-5162) This issue was discovered by Richard W.M. Jones (Red Hat). Bug Fix(es): * qemu-img calls were unrestricted by ulimit. oslo.concurrency has been updated to add support for process limits ('prlimit'), which is needed to fix the CVE-2015-5162 security vulnerability.
