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-2020-21050 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-2020-21050/ (Markdown: https://insights.sbomify.com/CVE-2020-21050/index.md)","id":"CVE-2020-21050","markdown":"https://insights.sbomify.com/CVE-2020-21050/index.md","name":"CVE-2020-21050","record":{"aliases":["DEBIAN-CVE-2020-21050","GHSA-v5qv-jjr8-5wpj","UBUNTU-CVE-2020-21050"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Libsixel image library","requires_auth":"none","summary":"A stack buffer overflow in Libsixel allows attackers to execute arbitrary code or cause denial of service via crafted GIF files.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"libsixel","vendor":"saitoha"}],"cvss":{"score":6.5,"severity":"medium","source":"nvd","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-787","name":"Out-of-bounds Write"}],"description":"Libsixel prior to v1.8.3 contains a stack buffer overflow in the function gif_process_raster at fromgif.c.","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-2020-21050","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2020"},"n_packages":0,"n_references":6,"next":{"headline":"Cross-site scripting in n/a","id":"CVE-2020-21052"},"packages":[],"prev":{"headline":"Denial of service in n/a","id":"CVE-2020-21049"},"products":["n/a"],"published":"2021-09-14","related":[{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2019-19635","kev_date_added":null,"published":"2019-12-08"},{"cvss_score":9.8,"headline":"Integer overflow in n/a","id":"CVE-2019-19636","kev_date_added":null,"published":"2019-12-08"},{"cvss_score":9.8,"headline":"Integer overflow in n/a","id":"CVE-2019-19637","kev_date_added":null,"published":"2019-12-08"},{"cvss_score":9.8,"headline":"Integer overflow in n/a","id":"CVE-2019-19638","kev_date_added":null,"published":"2019-12-08"},{"cvss_score":8.8,"headline":"Memory corruption in n/a","id":"CVE-2022-27044","kev_date_added":null,"published":"2022-04-08"},{"cvss_score":8.8,"headline":"Use after free in n/a","id":"CVE-2022-27046","kev_date_added":null,"published":"2022-04-08"},{"cvss_score":8.8,"headline":"Memory corruption in n/a","id":"CVE-2020-21547","kev_date_added":null,"published":"2021-09-17"}],"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 buffer overflow in Libsixel allows attackers to execute arbitrary code or cause denial of service via crafted GIF files.","url":"https://insights.sbomify.com/CVE-2020-21050/"}
