It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2013-4463 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- nova (PyPI): affected all versions; fixed in 12.0.0a0\n- nova (PyPI): affected all versions; fixed in 12.0.0a0\n- nova (PyPI): affected all versions; fixed in 12.0.0a0\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2013-4463/ (Markdown: https://insights.sbomify.com/CVE-2013-4463/index.md)","id":"CVE-2013-4463","markdown":"https://insights.sbomify.com/CVE-2013-4463/index.md","name":"CVE-2013-4463","record":{"aliases":["DEBIAN-CVE-2013-4463","GHSA-5644-2v3h-5w4x","PYSEC-2026-865"],"analysis":{"component_type":"cloud_service","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"OpenStack Compute","requires_auth":"low_privilege","summary":"Local users can cause host disk exhaustion via compressed QCOW2 images in OpenStack Compute, requiring patches to prevent denial of service.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"folsom","vendor":"openstack"},{"product":"grizzly","vendor":"openstack"},{"product":"havana","vendor":"openstack"}],"cvss":{"score":2.1,"severity":"low","source":"nvd","vector":"AV:L/AC:L/Au:N/C:N/I:N/A:P","version":"2.0"},"cwes":[{"id":"CWE-399","name":null}],"description":"OpenStack Compute (Nova) Folsom, Grizzly, and Havana does not properly verify the virtual size of a QCOW2 image, which allows local users to cause a denial of service (host file system disk consumption) via a compressed QCOW2 image.
