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-2020-22043 in the wild and no public exploit code.\n\nAffected product: Ffmpeg Ffmpeg. 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-2020-22043/ (Markdown: https://insights.sbomify.com/CVE-2020-22043/index.md)","id":"CVE-2020-22043","markdown":"https://insights.sbomify.com/CVE-2020-22043/index.md","name":"CVE-2020-22043","record":{"aliases":["DEBIAN-CVE-2020-22043","GHSA-j6jv-rr9g-q9j6","UBUNTU-CVE-2020-22043"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"FFmpeg multimedia library","requires_auth":"none","summary":"A memory leak in FFmpeg's fifo_alloc_common function allows attackers to cause a denial of service by exhausting system memory.","user_interaction":"required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"ffmpeg","vendor":"ffmpeg"}],"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-401","name":"Missing Release of Memory after Effective Lifetime"}],"description":"A Denial of Service vulnerability exists in FFmpeg 4.2 due to a memory leak at the fifo_alloc_common function in libavutil/fifo.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":"Denial of service in n/a","id":"CVE-2020-22043","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"ffmpeg:ffmpeg","products":["ffmpeg:ffmpeg"],"type":"denial_of_service","year":"2020"},"n_packages":0,"n_references":1,"next":{"headline":"Denial of service in n/a","id":"CVE-2020-22044"},"packages":[],"prev":{"headline":"Denial of service in n/a","id":"CVE-2020-22042"},"products":["n/a"],"published":"2021-06-01","related":[{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2013-0864","kev_date_added":null,"published":"2013-11-23"},{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2013-0872","kev_date_added":null,"published":"2013-11-23"},{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2013-0873","kev_date_added":null,"published":"2013-11-23"},{"cvss_score":10,"headline":"Null dereference in n/a","id":"CVE-2013-4265","kev_date_added":null,"published":"2013-11-23"},{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2011-3937","kev_date_added":null,"published":"2013-01-05"},{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2012-2772","kev_date_added":null,"published":"2012-09-10"},{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2012-2775","kev_date_added":null,"published":"2012-09-10"}],"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 memory leak in FFmpeg's fifo_alloc_common function allows attackers to cause a denial of service by exhausting system memory.","url":"https://insights.sbomify.com/CVE-2020-22043/"}
