Title: OpenStack Nova vulnerabilities
Summary: Several security issues were fixed in OpenStack Nova.
George Shuklin discovered that OpenStack Nova incorrectly handled the
migration process. A remote authenticated user could use this issue to
consume resources, resulting in a denial of service. (CVE-2015-3241)
George Shuklin and Tushar Patil discovered that OpenStack Nova incorrectly
handled deleting instances. A remote authenticated user could use this
issue to consume disk resources, resulting in a denial of service.
(CVE-2015-3280)
It was discovered that OpenStack Nova incorrectly limited qemu-img calls. A
remote authenticated user could use this issue to consume resources,

OpenStack Compute (Nova) before 2015.1.3 (kilo) and 12.0.x before 12.0.1 (liberty), when using libvirt to spawn instances and use_cow_images is set to false, allow remote authenticated users to read arbitrary files by overwriting an instance disk with a crafted image and requesting a snapshot.
A flaw was discovered in the OpenStack Compute (nova) snapshot feature when using the libvirt driver. A compute user could overwrite an attached instance disk with a malicious header specifying a backing file, and then request a snapshot, causing a file from the compute host to be leaked. This flaw only affects LVM or Ceph setups, or setups using filesystem storage with "use_cow_images = False".

CVE-2015-7548 openstack-nova: Unprivileged API user can access host data using instance snapshot
A vulnerability in Nova instance snapshot was discovered. By overwriting the disk inside an instance with a malicious image and requesting a snapshot, an authenticated user would be able to read an arbitrary file from the compute host.
Host file needs to be readable by the nova user to be exposed except when using lvm for instance storage, when all files readable by root are exposed. Only setups using libvirt to spawn instances are vulnerable. Of these, setups which use filesystem storage, and do not set "use_cow_images = False" in Nova configuration are not affected. Setups which use ceph, lvm, or ploop for instance storage, and setups which use filesystem storage with "use_cow_images = Fals
