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-2026-96642/ (Markdown: https://insights.sbomify.com/CVE-2026-96642/index.md)","id":"CVE-2026-96642","markdown":"https://insights.sbomify.com/CVE-2026-96642/index.md","name":"CVE-2026-96642","record":{"aliases":["BIT-pillow-2026-96642","DEBIAN-CVE-2026-96642","ECHO-274d-5de4-fefd","GHSA-3j72-p6qg-6xp7","PYSEC-2026-4341","ROOT-APP-PYPI-CVE-2026-96642","UBUNTU-CVE-2026-96642"],"analysis":null,"analysis_generated_by":null,"assigner":"GitHub_M","cpe":[{"product":"pillow","vendor":"python"}],"cvss":{"score":7.1,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:P/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-835","name":"Loop with Unreachable Exit Condition"}],"description":"Pillow is a Python imaging library. Prior to 13.0.0, the TarIO initializer in src/PIL/TarIO.py accepts a negative octal member size and computes a backward seek that returns to the same 512-byte header. When the requested member name does not match, the parser repeatedly reads that header, consumes a full CPU core, and never returns. TarIO is reached only when an application directly uses PIL.TarIO.TarIO rather than the default Image.open() path.
