Releases

• Ubuntu 22.10
• Ubuntu 22.04 LTS
• Ubuntu 20.04 LTS

Packages

• nova - OpenStack Compute cloud infrastructure

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.

• python3-nova - 3:26.1.0-0ubuntu1

Ubuntu 22.04
