OpenStack Nova has a vulnerability in the handling of encrypted volumes. 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. All Nova installations supporting encrypted volumes are affected.
