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-2021-33815 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-2021-33815/ (Markdown: https://insights.sbomify.com/CVE-2021-33815/index.md)","id":"CVE-2021-33815","markdown":"https://insights.sbomify.com/CVE-2021-33815/index.md","name":"CVE-2021-33815","record":{"aliases":["CLEANSTART-2024-LU46307","GHSA-gcpj-pp7m-cw8v","JLSEC-2025-114"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"FFmpeg media library","requires_auth":"none","summary":"An out-of-bounds array access in FFmpeg's EXR decoder allows attackers to cause memory corruption, potentially leading to code execution or crashes.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"ffmpeg","vendor":"ffmpeg"}],"cvss":{"score":8.8,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-129","name":"Improper Validation of Array Index"}],"description":"dwa_uncompress in libavcodec/exr.c in FFmpeg 4.4 allows an out-of-bounds array access because dc_count is not strictly checked.","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-2021-33815","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"ffmpeg:ffmpeg","products":["ffmpeg:ffmpeg"],"type":"memory_corruption","year":"2021"},"n_packages":0,"n_references":2,"next":{"headline":"Dolibarr remote PHP code execution","id":"CVE-2021-33816"},"packages":[],"prev":{"headline":"XML External Entity (XXE) Injection in JDOM","id":"CVE-2021-33813"},"products":["n/a"],"published":"2021-06-03","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":"2024-08-03","vendors":["n/a"]},"summary":"An out-of-bounds array access in FFmpeg's EXR decoder allows attackers to cause memory corruption, potentially leading to code execution or crashes.","url":"https://insights.sbomify.com/CVE-2021-33815/"}
