[Bug 2085851] Please test proposed package

[James Page]

Hello Marcin, or anyone else affected,

Accepted cinder into yoga-proposed. The package will build now and be
available in the Ubuntu Cloud Archive in a few hours, and then in the
-proposed repository.

Please help us by testing this new package. To enable the -proposed
repository:

  sudo add-apt-repository cloud-archive:yoga-proposed
  sudo apt-get update

Your feedback will aid us getting this update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested, and change the tag
from verification-yoga-needed to verification-yoga-done. If it does not
fix the bug for you, please add a comment stating that, and change the
tag to verification-yoga-failed. In either case, details of your testing
will help us make a better decision.

Further information regarding the verification process can be found at
https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in
advance!

Bug description:
  Ubuntu Jammy cinder package version 2:20.3.1-0ubuntu1.4 [1] backported fix [2] for the LP#2059809 [3] (the CVE-2024-32498 fix).
  The upstream fix [2] calls the `format_inspector.detect_file_format` with elevated privileges [4], however the code in the Ubuntu package does not [5]. Instead it calls the `format_inspector.detect_file_format` without using privsep. That is causing the following error when creating qcow image from volume (using purestorage driver):
