PYSEC-2026-861

OpenStack Nova instance migration process does not stop when instance is deleted

Quick fix

PYSEC-2026-861 — nova: upgrade to the fixed version with the command below.

pip install --upgrade 'nova>=12.0.0.0b3'

Details

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.
