Package        : nova
Version        : 2:22.4.0-1~deb11u5
CVE ID         : CVE-2024-32498 CVE-2024-40767
Debian Bug     : 1074762

Martin Kaesberger discovered a vulnerability which affects multiple
OpenStack components (Nova, Glance and Cinder): Malformed QCOW2 disk
images may result in the disclosure of arbitrary files.

Arnaud Morin later discovered that the initial fix was not sufficient,
and that nova was still vulnerable with some VM images types.

For Debian 11 bullseye, these problems have been fixed in version
2:22.4.0-1~deb11u5.

We recommend that you upgrade your nova packages.
