Sicherheitslücken: 54
OpenStack Compute (Nova) before 2014.2.4 (juno) and 2015.1.x before 2015.1.2 (kilo) do not properly apply security group changes, which allows remote attackers to bypass intended restriction by leveraging an instance that was running when the change was made.
OpenStack Compute (nova) before 2014.2.4 (juno) and 2015.1.x before 2015.1.2 (kilo) does not properly delete instances from compute nodes, which allows remote authenticated users to cause a denial of service (disk consumption) by deleting instances while in the resize state.
OpenStack Compute (nova) 2015.1 through 2015.1.1, 2014.2.3, and earlier does not stop the migration process when the instance is deleted, which allows remote authenticated users to cause a denial of service (disk, network, and other resource consumption) by resizing and then deleting an instance.
OpenStack Compute (Nova) before 2014.1.4, 2014.2.x before 2014.2.3, and kilo before kilo-3 does not validate the origin of websocket requests, which allows remote attackers to hijack the authentication of users for access to consoles via a crafted webpage.
The VMware driver in OpenStack Compute (Nova) before 2014.1.4 allows remote authenticated users to cause a denial of service (disk consumption) by deleting an instance in the resize state.
OpenStack Compute (Nova) before 2014.1.4 and 2014.2.x before 2014.2.1 allows remote authenticated users to cause a denial of service (CPU consumption) via an IP filter in a list active servers API request.
The VMWare driver in OpenStack Compute (Nova) before 2014.1.3 allows remote authenticated users to bypass the quota limit and cause a denial of service (resource consumption) by putting the VM into the rescue state, suspending it, which puts into an ERROR state, and then deleting the image. NOTE: this vulnerability exists because of an incomplete fix for CVE-2014-2573.
api/metadata/handler.py in OpenStack Compute (Nova) before 2013.2.4, 2014.x before 2014.1.2, and Juno before Juno-2, when proxying metadata requests through Neutron, makes it easier for remote attackers to guess instance ID signatures via a brute-force attack that relies on timing differences in responses to instance metadata requests.
The instance rescue mode in OpenStack Compute (Nova) 2013.2 before 2013.2.3 and Icehouse before 2014.1, when using libvirt to spawn images and use_cow_images is set to false, allows remote authenticated users to read certain compute host files by overwriting an instance disk with a crafted image.
The Nova EC2 API security group implementation in OpenStack Compute (Nova) 2013.1 before 2013.2.4 and icehouse before icehouse-rc2 does not enforce RBAC policies for (1) add_rules, (2) remove_rules, (3) destroy, and other unspecified methods in compute/api.py when using non-default policies, which allows remote authenticated users to gain privileges via these API requests.
The VMWare driver in OpenStack Compute (Nova) 2013.2 through 2013.2.2 does not properly put VMs into RESCUE status, which allows remote authenticated users to bypass the quota limit and cause a denial of service (resource consumption) by requesting the VM be put into rescue and then deleting the image.
The libvirt driver in OpenStack Compute (Nova) before 2013.2.2 and icehouse before icehouse-2 allows remote authenticated users to cause a denial of service (disk consumption) by creating and deleting instances with unique os_type settings, which triggers the creation of a new ephemeral disk backing file.
The i_create_images_and_backing (aka create_images_and_backing) method in libvirt driver in OpenStack Compute (Nova) Grizzly, Havana, and Icehouse, when using KVM live block migration, does not properly create all expected files, which allows attackers to obtain snapshot root disk contents of other users via ephemeral storage.
OpenStack Compute (Nova) Folsom, Grizzly, and Havana does not properly verify the virtual size of a QCOW2 image, which allows local users to cause a denial of service (host file system disk consumption) via a compressed QCOW2 image. NOTE: this issue is due to an incomplete fix for CVE-2013-2096.
OpenStack Compute (Nova) Grizzly 2013.1.4, Havana 2013.2.1, and earlier uses world-writable and world-readable permissions for the temporary directory used to store live snapshots, which allows local users to read and modify live snapshots.
Interaction error in OpenStack Nova and Neutron before Havana 2013.2.1 and icehouse-1 does not validate the instance ID of the tenant making a request, which allows remote tenants to obtain sensitive metadata by spoofing the device ID that is bound to a port, which is not properly handled by (1) api/metadata/handler.py in Nova and (2) the neutron-metadata-agent (agent/metadata/agent.py) in Neutron.
The XenAPI backend in OpenStack Compute (Nova) Folsom, Grizzly, and Havana before 2013.2 does not properly apply security groups (1) when resizing an image or (2) during live migration, which allows remote attackers to bypass intended restrictions.
OpenStack Compute (Nova) Folsom, Grizzly, and Havana, when use_cow_images is set to False, does not verify the virtual size of a QCOW2 image, which allows local users to cause a denial of service (host file system disk consumption) by transferring an image with a large virtual size that does not contain a large amount of data from Glance. NOTE: this issue is due to an incomplete fix for CVE-2013-2096.
Algorithmic complexity vulnerability in OpenStack Compute (Nova) before 2013.1.3 and Havana before havana-3 does not properly handle network source security group policy updates, which allows remote authenticated users to cause a denial of service (nova-network consumption) via a large number of server-creation operations, which triggers a large number of update requests.
The "create an instance" API in OpenStack Compute (Nova) Folsom, Grizzly, and Havana does not properly enforce the os-flavor-access:is_public property, which allows remote authenticated users to boot arbitrary flavors by guessing the flavor id. NOTE: this issue is due to an incomplete fix for CVE-2013-2256.
