OpenStack Nova: Nova scheduler hint injection bypasses Placement resource claims and scheduling constraints

In OpenStack Nova before 33.0.2, the server create API does not strip certain hint data. The resulting instance has no Placement allocation.

OpenStack Cinder, Glance, and Nova vulnerable to arbitrary file access

An issue was discovered in OpenStack Cinder through 24.0.0, Glance before 28.0.2, and Nova before 29.0.3. Arbitrary file access can occur via custom QCOW2 external data. By supplying a crafted QCOW2 image that references a specific data file path, an authenticated user may convince systems to return a copy of that file's contents from the server, resulting in unauthorized access to potentially sensitive data. All Cinder and Nova deployments are affected; only Glance deployments with image conver

OpenStack Cinder, glance, and Nova vulnerable to Path Traversal

An issue was discovered in OpenStack Cinder before 19.1.2, 20.x before 20.0.2, and 21.0.0; Glance before 23.0.1, 24.x before 24.1.1, and 25.0.0; and Nova before 24.1.2, 25.x before 25.0.2, and 26.0.0. By supplying a specially created VMDK flat image that references a specific backing file path, an authenticated user may convince systems to return a copy of that file's contents from the server, resulting in unauthorized access to potentially sensitive data.

OpenStack Nova Changing vnic_type breaks compute service restart

An issue was discovered in OpenStack Nova before 23.2.2, 24.x before 24.1.2, and 25.x before 25.0.2. By creating a neutron port with the direct vnic_type, creating an instance bound to that port, and then changing the vnic_type of the bound port to macvtap, an authenticated user may cause the compute service to fail to restart, resulting in a possible denial of service. Only Nova deployments configured with SR-IOV are affected.

OpenStack Nova Live migration fails to update persistent domain XML

An issue was discovered in Guest.migrate in virt/libvirt/guest.py in OpenStack Nova before 19.3.1, 20.x before 20.3.1, and 21.0.0. By performing a soft reboot of an instance that has previously undergone live migration, a user may gain access to destination host devices that share the same paths as host devices previously referenced by the virtual machine on the source host. This can include block devices that map to different Cinder volumes at the destination than at the source. Only deployment

OpenStack Nova Exposure of Sensitive Information to an Unauthorized Actor

OpenStack Nova before 2012.1 allows someone with access to an EC2_ACCESS_KEY (equivalent to a username) to obtain the EC2_SECRET_KEY (equivalent to a password). Exposing the EC2_ACCESS_KEY via http or tools that allow man-in-the-middle over https could allow an attacker to easily obtain the EC2_SECRET_KEY. An attacker could also presumably brute force values for EC2_ACCESS_KEY.

OpenStack Nova Server Resource Faults Leak External Exception Details

An issue was discovered in OpenStack Nova before 17.0.12, 18.x before 18.2.2, and 19.x before 19.0.2. If an API request from an authenticated user ends in a fault condition due to an external exception, details of the underlying environment may be leaked in the response, and could include sensitive configuration or other data.

OpenStack Nova Denial of service attack on the compute host

An issue was discovered in OpenStack Nova 15.x through 15.1.0 and 16.x through 16.1.1. By detaching and reattaching an encrypted volume, an attacker may access the underlying raw volume and corrupt the LUKS header, resulting in a denial of service attack on the compute host. (The same code error also results in data loss, but that is not a vulnerability because the user loses their own data.) All Nova setups supporting encrypted volumes are affected.

OpenStack Nova DoS by rebuilding the same instance with a new image multiple times

An issue was discovered in the default FilterScheduler in OpenStack Nova 16.0.3. By repeatedly rebuilding an instance with new images, an authenticated user may consume untracked resources on a hypervisor host leading to a denial of service, aka doubled resource allocations. This regression was introduced with the fix for OSSA-2017-005 (CVE-2017-16239); however, only Nova stable/pike or later deployments with that fix applied and relying on the default FilterScheduler are affected.

OpenStack Nova Filter Scheduler Bypass

In OpenStack Nova through 14.0.9, 15.x through 15.0.7, and 16.x through 16.0.2, by rebuilding an instance, an authenticated user may be able to circumvent the Filter Scheduler bypassing imposed filters (for example, the ImagePropertiesFilter or the IsolatedHostsFilter). All setups using Nova Filter Scheduler are affected. Because of the regression described in Launchpad Bug #1732947, the preferred fix is a 14.x version after 14.0.10, a 15.x version after 15.0.8, or a 16.x version after 16.0.3.

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.
