It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2025-59731 in the wild and no public exploit code.\n\nAffected product: 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-2025-59731/ (Markdown: https://insights.sbomify.com/CVE-2025-59731/index.md)","id":"CVE-2025-59731","markdown":"https://insights.sbomify.com/CVE-2025-59731/index.md","name":"CVE-2025-59731","record":{"aliases":["DEBIAN-CVE-2025-59731","GHSA-p7r5-qh99-qchm","JLSEC-2026-644","MINI-rcv4-m48f-797r"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution","denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"FFmpeg media library","requires_auth":"low_privilege","summary":"A heap-buffer-overflow in FFmpeg's EXR decoder allows attackers to execute arbitrary code or cause denial of service via crafted files.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Google","cpe":[],"cvss":{"score":6.9,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:A/AC:H/AT:N/PR:L/UI:P/VC:H/VI:H/VA:N/SC:H/SI:H/SA:N","version":"4.0"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"}],"description":"When decoding an OpenEXR file that uses DWAA or DWAB compression, the specified raw length of run-length-encoded data is not checked when using it to calculate the output data.\n\nWe read rle_raw_size from the input file at [0], we decompress and decode into the buffer td-\u003erle_raw_data of size rle_raw_size at [1], and then at [2] we will access entries in this buffer up to (td-\u003exsize - 1) * (td-\u003eysize - 1) + rle_raw_size / 2, which may exceed rle_raw_size.\n\nWe recommend upgrading to version 8.0 or beyond.","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":"Heap-buffer-overflow write in FFmpeg EXR dwa_uncompress","id":"CVE-2025-59731","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2025"},"n_packages":0,"n_references":1,"next":{"headline":"Heap-buffer-overflow write in FFmpeg EXR dwa_uncompress","id":"CVE-2025-59732"},"packages":[],"prev":{"headline":"Heap-buffer-overflow write in FFmpeg SANM decoding due to lack of bounds-checking in old_codec48","id":"CVE-2025-59730"},"products":["FFmpeg"],"published":"2025-10-06","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-02-26","vendors":["FFmpeg"]},"summary":"A heap-buffer-overflow in FFmpeg's EXR decoder allows attackers to execute arbitrary code or cause denial of service via crafted files.","url":"https://insights.sbomify.com/CVE-2025-59731/"}
