    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.

    For the detailed security status of nova please refer to
    its security tracker page at:
    https://security-tracker.debian.org/tracker/nova
