An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2021-39432 exists.\n\nAffected packages and fixed versions:\n- diplib (PyPI): affected all versions; fixed in 3.1.0\n- diplib (PyPI): affected all versions; fixed in 3.1.0\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-2021-39432/ (Markdown: https://insights.sbomify.com/CVE-2021-39432/index.md)","id":"CVE-2021-39432","markdown":"https://insights.sbomify.com/CVE-2021-39432/index.md","name":"CVE-2021-39432","record":{"aliases":["GHSA-xf2w-5673-h6ww"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Python image library","requires_auth":"none","summary":"A double free vulnerability in diplib allows attackers to cause denial of service or potentially execute arbitrary code.","user_interaction":"required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"diplib","vendor":"diplib"}],"cvss":{"score":6.5,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-415","name":"Double Free"},{"id":"CWE-416","name":"Use After Free"}],"description":"diplib v3.0.0 is vulnerable to Double Free.","ecosystems":["PyPI"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":true,"headline":"diplib Double Free","id":"CVE-2021-39432","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"PyPI","product":null,"products":[],"type":"use_after_free","year":"2021"},"n_packages":2,"n_references":2,"next":{"headline":"Path traversal in n/a","id":"CVE-2021-39433"},"packages":[{"ecosystem":"PyPI","fixed":["3.1.0"],"introduced":["0"],"last_affected":[],"package":"diplib","purl":null,"source":"GHSA-xf2w-5673-h6ww"},{"ecosystem":"PyPI","fixed":["3.1.0"],"introduced":["0"],"last_affected":[],"package":"diplib","purl":"pkg:pypi/diplib","source":"GHSA-xf2w-5673-h6ww"}],"prev":{"headline":"Cross-site scripting in n/a","id":"CVE-2021-39428"},"products":["n/a"],"published":"2022-11-04","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-05-02","vendors":["n/a"]},"summary":"A double free vulnerability in diplib allows attackers to cause denial of service or potentially execute arbitrary code.","url":"https://insights.sbomify.com/CVE-2021-39432/"}
