CVE-2017-18191 (opens in a new tab)How to fix?
Upgrade RHEL:7 openstack-nova-console to version 1:16.1.4-6.el7ost or higher.
This issue was patched in RHSA-2018:2332.
NVD Description
Note: Versions mentioned in the description apply only to the upstream openstack-nova-console package and not the openstack-nova-console package as distributed by RHEL.
See How to fix? for RHEL:7 relevant fixed versions and status.
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.
