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.

A denial of service flaw was found in the OpenStack Compute instance
migration process. Because the migration process does not terminate
when an instance is deleted, an authenticated user could bypass
user quota and deplete all available disk space by repeatedly re-sizing
and deleting an instance. (CVE-2015-3241)

A flaw was found in the way OpenStack Compute handled the resize
state. If an authenticated user deleted an instance while it was in the
resize state, it could cause the original instance to not be deleted from
the compute node it was running on, allowing the user to cause a denial
of service. (CVE-2015-3280)

Note: CVE-2015-3241 was already addressed in Red Hat Enterprise Linux
OpenStack Platform 7.0 in a previous release.

Red Hat would like to thank the OpenStack project for reporting these
issues. Upstream acknowledges George Shuklin of Webzilla LTD as the
original reporter of CVE-2015-3241, and George Shuklin from Webzilla LTD
and Tushar Patil from NTT DATA, Inc. as the original reporters of
CVE-2015-3280.

All openstack-nova users are advised to upgrade to these updated packages,
which correct these issues and add these enhancements.
