OpenStack Compute (Nova) allows remote authenticated users to obtain sensitive information

OpenStack Compute Nova before 2013.1.3 and Havana before havana-2 does not properly enforce the os-flavor-access:ispublic property, which allows remote authenticated users to obtain sensitive information flavor properties, boot arbitrary flavors, and possibly have other unspecified impacts by...

OpenStack Compute (Nova)'s VMWare driver vulnerable to denial of service

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: thi...

PYSEC-2026-873 OpenStack Nova live snapshots use an insecure local directory

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...

PYSEC-2026-867 OpenStack Compute (Nova) allows remote attackers to bypass intended restriction

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...

PYSEC-2026-861 OpenStack Nova instance migration process does not stop when instance is deleted

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 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...

PYSEC-2026-692 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...
