First published: Tue Feb 20 2018(Updated: )
OpenStack Nova 15.x through 15.1.0 and 16.x through 16.0.4 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 setups supporting encrypted volumes are affected.
