It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of OSV-2025-591 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- mpv (OSS-Fuzz): affected all versions; no fix listed\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/OSV-2025-591/ (Markdown: https://insights.sbomify.com/OSV-2025-591/index.md)","id":"OSV-2025-591","markdown":"https://insights.sbomify.com/OSV-2025-591/index.md","name":"OSV-2025-591","record":{"aliases":[],"analysis":{"component_type":"library","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"FFmpeg media library","requires_auth":"none","summary":"A memory corruption vulnerability in FFmpeg's mov_read_header function allows attackers to cause a denial of service via crafted media files.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"OSS-Fuzz report: https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=435536867\n\n```\nCrash type: UNKNOWN READ\nCrash state:\nmov_read_header\navformat_open_input\ndemux_open_lavf\n```","ecosystems":["OSS-Fuzz"],"exploits":{"exploitdb":null,"first_seen":null,"github_poc":null,"max_poc_stars":null,"metasploit":null,"nuclei":null,"refs":[],"tier":null},"has_fix":false,"headline":"UNKNOWN READ in mov_read_header","id":"OSV-2025-591","indexable":true,"kev":null,"kind":"advisory","links":{"ecosystem":"OSS-Fuzz","product":null,"products":[],"type":"memory_corruption","year":"2025"},"n_packages":1,"n_references":null,"packages":[{"ecosystem":"OSS-Fuzz","fixed":[],"introduced":[],"last_affected":[],"package":"mpv","purl":"pkg:generic/mpv","source":"OSV-2025-591"}],"products":null,"published":"2025-08-02","related":[],"sources":[{"class":"attribution","licence":"CC BY 4.0","name":"OSS-Fuzz","prefix":"OSV"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":null,"updated":null,"vendors":null},"summary":"A memory corruption vulnerability in FFmpeg's mov_read_header function allows attackers to cause a denial of service via crafted media files.","url":"https://insights.sbomify.com/OSV-2025-591/"}
