CVE-2024-0450 is a medium-severity denial of service vulnerability in CPython, published on 19 Mar 2024. It can only be exploited from the same machine or local network, with no action from the victim. ### Official description An issue was found in the CPython `zipfile` module affecting versions 3.12.1, 3.11.7, 3.10.13, 3.9.18, and 3.8.18 and prior. The zipfile module is vulnerable to “quoted-overlap” zip-bombs which exploit the zip format to create a zip-bomb with a high compression ratio. The fixed versions of CPython makes the zipfile module reject zip archives which overlap entries in the archive.

What it is: CVE-2024-0450 is a medium-severity denial of service vulnerability in CPython, published on 19 Mar 2024. It can only be exploited from the same machine or local network, with no action from the victim. Exploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2024-0450 exists. Affected packages and fixed versions: - libpython (Bitnami): affected all versions; fixed in 3.8.19, 3.9.19, 3.10.14, 3.11.8, 3.12.2 - python (Bitnami): affected all versions; fixed in 3.8.19, 3.9.19, 3.10.14, 3.11.8, 3.12.2 - python-min (Bitnami): affected all versions; fixed in 3.8.19, 3.9.19, 3.10.14, 3.11.8, 3.12.2 Task: 1. 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. 2. 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. 3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead. 4. Run the tests and summarise what changed and why. 5. If nothing in the project is affected, say so and change nothing.
