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-2020-21682 in the wild and no public exploit code.\n\nAffected product: n/a. 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-2020-21682/ (Markdown: https://insights.sbomify.com/CVE-2020-21682/index.md)","id":"CVE-2020-21682","markdown":"https://insights.sbomify.com/CVE-2020-21682/index.md","name":"CVE-2020-21682","record":{"aliases":["DEBIAN-CVE-2020-21682","GHSA-f38c-75f7-6g7p","UBUNTU-CVE-2020-21682"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"fig2dev image converter","requires_auth":"none","summary":"Attackers can cause a denial of service via a global buffer overflow in fig2dev when converting xfig files to ge format.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"fig2dev","vendor":"fig2dev_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-120","name":"Buffer Copy without Checking Size of Input"}],"description":"A global buffer overflow in the set_fill component in genge.c of fig2dev 3.2.7b allows attackers to cause a denial of service (DOS) via converting a xfig file into ge format.","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-2020-21682","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2020"},"n_packages":0,"n_references":1,"next":{"headline":"Memory corruption in n/a","id":"CVE-2020-21683"},"packages":[],"prev":{"headline":"Memory corruption in n/a","id":"CVE-2020-21681"},"products":["n/a"],"published":"2021-08-10","related":[{"cvss_score":7.8,"headline":"Xfig: xfig: stack-overflow allows possible code execution via local input manipulation","id":"CVE-2025-46397","kev_date_added":null,"published":"2025-04-23"},{"cvss_score":6.6,"headline":"fig2dev float point exception","id":"CVE-2025-31162","kev_date_added":null,"published":"2025-03-28"},{"cvss_score":6.6,"headline":"fig2dev segmentation fault","id":"CVE-2025-31163","kev_date_added":null,"published":"2025-03-28"},{"cvss_score":6.6,"headline":"fig2dev heap-buffer overflow","id":"CVE-2025-31164","kev_date_added":null,"published":"2025-03-28"},{"cvss_score":5.5,"headline":"Xfig: fig2dev stack-overflow via read_objects","id":"CVE-2025-46398","kev_date_added":null,"published":"2025-04-23"},{"cvss_score":5.5,"headline":"Xfig: transfig: fig2dev segmentation fault vulnerability","id":"CVE-2025-46399","kev_date_added":null,"published":"2025-04-23"},{"cvss_score":5.5,"headline":"Xfig: fig2dev segmentation fault in read_arcobject","id":"CVE-2025-46400","kev_date_added":null,"published":"2025-04-23"}],"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":"Attackers can cause a denial of service via a global buffer overflow in fig2dev when converting xfig files to ge format.","url":"https://insights.sbomify.com/CVE-2020-21682/"}
