12.0.0a0- Upgrade nova to this version or later
Description
OpenStack Compute (Nova) Folsom, Grizzly, and Havana, when use_cow_images is set to False, does not verify the virtual size of a QCOW2 image, which allows local users to cause a denial of service (host file system disk consumption) by transferring an image with a large virtual size that does not contain a large amount of data from Glance. NOTE: this issue is due to an incomplete fix for CVE-2013-2096.
Affected versions
PyPI
| Package | Vulnerable | Fixed in |
|---|---|---|
| nova | < 12.0.0a0 |
12.0.0a0 |
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"
