2. Relevant releases/architectures:

 

Red Hat Enterprise Linux OpenStack Platform 5.0 for RHEL 7 - noarch

 

3. Description:

 

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.

 

An information-exposure flaw was found in the OpenStack Compute (nova)

resize and migrate functionality. An authenticated user could write a

malicious qcow header to an ephemeral or root disk, referencing a block

device as a backing file. With a subsequent resize or migration, file

system content on the specified device would be leaked to the user. Only

setups using libvirt with raw storage and "use_cow_images = False" were

affected. (CVE-2016-2140)

 

This issue was discovered by Matthew Booth of Red Hat.

 

All openstack-nova users are advised to upgrade to these updated packages,

which correct this issue.
