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-2018-13303 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-2018-13303/ (Markdown: https://insights.sbomify.com/CVE-2018-13303/index.md)","id":"CVE-2018-13303","markdown":"https://insights.sbomify.com/CVE-2018-13303/index.md","name":"CVE-2018-13303","record":{"aliases":["CLEANSTART-2024-DF56851","DEBIAN-CVE-2018-13303","GHSA-rrxj-m39q-79v3","UBUNTU-CVE-2018-13303"],"analysis":{"component_type":"library","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"FFmpeg media library","requires_auth":"none","summary":"A missing check in FFmpeg's AC3 parser allows attackers to cause a denial of service via a crafted AVI file.","user_interaction":"required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"ffmpeg","vendor":"ffmpeg"}],"cvss":{"score":6.5,"severity":"medium","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H","version":"3.0"},"cwes":[{"id":"CWE-476","name":"NULL Pointer Dereference"}],"description":"In FFmpeg 4.0.1, a missing check for failure of a call to init_get_bits8() in the avpriv_ac3_parse_header function in libavcodec/ac3_parser.c may trigger a NULL pointer dereference while converting a crafted AVI file to MPEG4, leading to 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":"Null dereference in n/a","id":"CVE-2018-13303","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"ffmpeg:ffmpeg","products":["ffmpeg:ffmpeg"],"type":"null_dereference","year":"2018"},"n_packages":0,"n_references":2,"next":{"headline":"Denial of service in n/a","id":"CVE-2018-13304"},"packages":[],"prev":{"headline":"Memory corruption in n/a","id":"CVE-2018-13302"},"products":["n/a"],"published":"2018-07-05","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":"2024-08-05","vendors":["n/a"]},"summary":"A missing check in FFmpeg's AC3 parser allows attackers to cause a denial of service via a crafted AVI file.","url":"https://insights.sbomify.com/CVE-2018-13303/"}
