An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2020-36407 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- avif (PyPI): affected all versions up to 0.8.0; no fix listed\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-2020-36407/ (Markdown: https://insights.sbomify.com/CVE-2020-36407/index.md)","id":"CVE-2020-36407","markdown":"https://insights.sbomify.com/CVE-2020-36407/index.md","name":"CVE-2020-36407","record":{"aliases":["DEBIAN-CVE-2020-36407","GHSA-5fvj-fm55-q8qx","PYSEC-2021-892"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"AVIF image library","requires_auth":"none","summary":"An out-of-bounds write in libavif allows attackers to execute arbitrary code or cause denial of service via crafted AVIF images.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"libavif","vendor":"aomedia"}],"cvss":{"score":8.8,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"}],"description":"libavif 0.8.0 and 0.8.1 has an out-of-bounds write in avifDecoderDataFillImageGrid.","ecosystems":["PyPI"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Memory corruption in n/a","id":"CVE-2020-36407","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"PyPI","product":null,"products":[],"type":"memory_corruption","year":"2020"},"n_packages":1,"n_references":3,"next":{"headline":"Cross-site scripting in n/a","id":"CVE-2020-36408"},"packages":[{"ecosystem":"PyPI","fixed":[],"introduced":["0"],"last_affected":["0.8.0","0.8.1"],"package":"avif","purl":"pkg:pypi/avif","source":"PYSEC-2021-892"}],"prev":{"headline":"Memory corruption in n/a","id":"CVE-2020-36406"},"products":["n/a"],"published":"2021-07-01","related":[{"cvss_score":4.5,"headline":"Integer overflow in libavif","id":"CVE-2025-48174","kev_date_added":null,"published":"2025-05-16"},{"cvss_score":4.5,"headline":"Integer overflow in libavif","id":"CVE-2025-48175","kev_date_added":null,"published":"2025-05-16"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"PyPA Advisory Database","prefix":"PYSEC"},{"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":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-04","vendors":["n/a"]},"summary":"An out-of-bounds write in libavif allows attackers to execute arbitrary code or cause denial of service via crafted AVIF images.","url":"https://insights.sbomify.com/CVE-2020-36407/"}
