12.0.0a0- Upgrade nova to this version or later
Description
OpenStack Compute (Nova) Folsom before 2012.2.2 and Grizzly, when using libvirt and LVM backed instances, does not properly clear physical volume (PV) content when reallocating for instances, which allows attackers to obtain sensitive information by reading the memory of the previous logical volume (LV).
Affected versions

| Package | Vulnerable | Fixed in |
|---|---|---|
| nova | < 12.0.0a0 |
12.0.0a0 |
| nova | all versions |
No fix yet |
| nova | See the source repository's commits | No fix yet |
How to fix
Move to the fixed version or later with your package manager, update the lockfile, and run your tests. If the package only arrives through another dependency, upgrade that dependency first. If none of its releases pulls a fixed version yet, force the version with your package manager's override.
nova PyPI → 12.0.0a0
- pip
pip install --upgrade "nova>=12.0.0a0"- poetry
poetry add "nova>=12.0.0a0"- uv
uv add "nova>=12.0.0a0"

Weakness
CWE-200: Exposure of Sensitive Information to an Unauthorized Actor
The product exposes sensitive information to an actor that is not explicitly authorized to have access to that information.
How to prevent it
- Architecture and Design: Compartmentalize the system to have "safe" areas where trust boundaries can be unambiguously drawn. Do not allow sensitive data to go outside of the trust boundary and always be careful when interfacing with a compartment outside of the safe area. Ensure that appropriate compartmentalization is built into the system design, and the compartmentalization allows for and reinforces privilege separation functionality. Architects and designers should rely on the principle of least privilege to decide the appropriate time to use privileges and the time to drop privileges.
