How to fix?

There is no fixed version for RHEL:7 openstack-nova-spicehtml5proxy.

NVD Description

Note: Versions mentioned in the description apply only to the upstream openstack-nova-spicehtml5proxy package and not the openstack-nova-spicehtml5proxy 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.
