Details

USN-5835-3 fixed vulnerabilities in Nova. This update provides the
corresponding updates for Ubuntu 18.04 LTS.

Original advisory details:

Guillaume Espanel, Pierre Libeau, Arnaud Morin, and Damien Rannou
discovered that Nova incorrectly handled VMDK image processing. An
authenticated attacker could possibly supply a specially crafted VMDK flat
image and obtain arbitrary files from the server containing sensitive
information.
