cinder vulnerability
=========================================================================
A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 22.10
- Ubuntu 22.04 LTS
- Ubuntu 20.04 LTS

Summary:

Cinder could be made to expose sensitive information.

Software Description:
- cinder: OpenStack storage service

Details:

Guillaume Espanel, Pierre Libeau, Arnaud Morin, and Damien Rannou
discovered that Cinder 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.

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 22.10:
   python3-cinder                  2:21.1.0-0ubuntu1

Ubuntu 22.04 LTS:
   python3-cinder                  2:20.1.0-0ubuntu1

Ubuntu 20.04 LTS:
   python3-cinder                  2:16.4.2-0ubuntu2.1

After a standard system update you need to restart Cinder to make all the
necessary changes.
