Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2025-9951 exists.\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-2025-9951/ (Markdown: https://insights.sbomify.com/CVE-2025-9951/index.md)","id":"CVE-2025-9951","markdown":"https://insights.sbomify.com/CVE-2025-9951/index.md","name":"CVE-2025-9951","record":{"aliases":["DEBIAN-CVE-2025-9951","GHSA-39q3-f8jq-v6mg","JLSEC-2026-648","UBUNTU-CVE-2025-9951"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"FFmpeg multimedia library","requires_auth":"low_privilege","summary":"Attackers can achieve remote code execution or cause denial of service via a heap buffer overflow in FFmpeg's JPEG2000 decoder.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Google","cpe":[],"cvss":{"score":7.2,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:H/AT:N/PR:L/UI:N/VC:N/VI:H/VA:H/SC:N/SI:H/SA:H","version":"4.0"},"cwes":[{"id":"CWE-122","name":"Heap-based Buffer Overflow"}],"description":"A heap-buffer-overflow write exists in jpeg2000dec FFmpeg which allows an attacker to potentially gain remote code execution or cause denial of service via the channel definition cdef atom of JPEG2000.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2026-07-19","github_poc":1,"max_poc_stars":0,"metasploit":0,"nuclei":0,"refs":[{"date":"2026-07-19T19:56:08Z","kind":"github_poc","ref":"https://github.com/fm0ss/cve-2025-9951-ffmpeg-jp2-poc","stars":0,"title":null}],"tier":"weaponised"},"has_fix":true,"headline":"Remote code execution via Heap Buffer Overflow in FFmpeg JPEG2000","id":"CVE-2025-9951","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":"Trinity Audio \u003c= 5.20.2 - Reflected Cross-Site Scripting","id":"CVE-2025-9952"},"packages":[],"prev":{"headline":"Error Log Viewer by BestWebSoft \u003c= 1.1.6 - Authenticated (Administrator+) Arbitrary File Read","id":"CVE-2025-9950"},"products":["FFmpeg"],"published":"2025-09-09","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)"},{"class":"open","licence":"CC0","name":"PoC-in-GitHub"}],"ssvc":{"automatable":"no","exploitation":"poc","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-02-26","vendors":["FFmpeg"]},"summary":"Attackers can achieve remote code execution or cause denial of service via a heap buffer overflow in FFmpeg's JPEG2000 decoder.","url":"https://insights.sbomify.com/CVE-2025-9951/"}
