Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2020-20448 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-2020-20448/ (Markdown: https://insights.sbomify.com/CVE-2020-20448/index.md)","id":"CVE-2020-20448","markdown":"https://insights.sbomify.com/CVE-2020-20448/index.md","name":"CVE-2020-20448","record":{"aliases":["DEBIAN-CVE-2020-20448","GHSA-rqxg-44wv-f888"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Multimedia processing library","requires_auth":"low_privilege","summary":"A remote attacker can cause a denial of service in FFmpeg via a divide-by-zero error in the rate control module.","user_interaction":"not_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:L/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-369","name":"Divide By Zero"}],"description":"FFmpeg 4.1.3 is affected by a Divide By Zero issue via libavcodec/ratecontrol.c, which allows a remote malicious user to cause a Denial of Service.","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-2020-20448","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":"Null dereference in n/a","id":"CVE-2020-20450"},"packages":[],"prev":{"headline":"Denial of service in n/a","id":"CVE-2020-20446"},"products":["n/a"],"published":"2021-05-25","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 remote attacker can cause a denial of service in FFmpeg via a divide-by-zero error in the rate control module.","url":"https://insights.sbomify.com/CVE-2020-20448/"}
