It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2020-18971 in the wild and no public exploit code.\n\nAffected product: Podofo Project Podofo. No package-level version data is available, so check the vendor advisory linked from the reference page.\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-2020-18971/ (Markdown: https://insights.sbomify.com/CVE-2020-18971/index.md)","id":"CVE-2020-18971","markdown":"https://insights.sbomify.com/CVE-2020-18971/index.md","name":"CVE-2020-18971","record":{"aliases":["DEBIAN-CVE-2020-18971","GHSA-xrmq-h6xp-2vgc","UBUNTU-CVE-2020-18971"],"analysis":{"component_type":"library","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"PoDoFo PDF library","requires_auth":"none","summary":"A stack-based buffer overflow in the PoDoFo library allows attackers to cause a denial of service via a crafted PDF file.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"podofo","vendor":"podofo_project"}],"cvss":{"score":5.5,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"}],"description":"Stack-based Buffer Overflow in PoDoFo v0.9.6 allows attackers to cause a denial of service via the component 'src/base/PdfDictionary.cpp:65'.","ecosystems":[],"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-2020-18971","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"podofo_project:podofo","products":["podofo_project:podofo"],"type":"memory_corruption","year":"2020"},"n_packages":0,"n_references":1,"next":{"headline":"Information disclosure in n/a","id":"CVE-2020-18972"},"packages":[],"prev":{"headline":"Cross-site request forgery in n/a","id":"CVE-2020-18964"},"products":["n/a"],"published":"2021-08-25","related":[{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2017-8378","kev_date_added":null,"published":"2017-05-01"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2015-8981","kev_date_added":null,"published":"2017-03-16"},{"cvss_score":8.8,"headline":"Memory corruption in n/a","id":"CVE-2023-31556","kev_date_added":null,"published":"2023-05-10"},{"cvss_score":8.8,"headline":"Use after free in n/a","id":"CVE-2023-31566","kev_date_added":null,"published":"2023-05-10"},{"cvss_score":8.8,"headline":"Memory corruption in n/a","id":"CVE-2023-31567","kev_date_added":null,"published":"2023-05-10"},{"cvss_score":8.8,"headline":"Memory corruption in n/a","id":"CVE-2023-31568","kev_date_added":null,"published":"2023-05-10"},{"cvss_score":8.8,"headline":"Null dereference in n/a","id":"CVE-2018-20751","kev_date_added":null,"published":"2019-02-04"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"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":"A stack-based buffer overflow in the PoDoFo library allows attackers to cause a denial of service via a crafted PDF file.","url":"https://insights.sbomify.com/CVE-2020-18971/"}
