An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-40417 in the wild and no public exploit code.\n\nAffected product: Blackmagic Design. 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-2021-40417/ (Markdown: https://insights.sbomify.com/CVE-2021-40417/index.md)","id":"CVE-2021-40417","markdown":"https://insights.sbomify.com/CVE-2021-40417/index.md","name":"CVE-2021-40417","record":{"aliases":["GHSA-9g9g-w89w-6r9g"],"analysis":{"component_type":"desktop_application","fix_type":"patch","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Blackmagic Design software","requires_auth":"none","summary":"An integer overflow in the DPDecoder service allows attackers to trigger a heap buffer overflow and execute arbitrary code via a crafted video file.","user_interaction":"not_required","vuln_class":"integer_overflow"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"talos","cpe":[{"product":"davinci_resolve","vendor":"blackmagicdesign"}],"cvss":{"score":9.8,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-190","name":"Integer Overflow or Wraparound"},{"id":"CWE-680","name":"Integer Overflow to Buffer Overflow"}],"description":"When parsing a file that is submitted to the DPDecoder service as a job, the service will use the combination of decoding parameters that were submitted with the job along with fields that were parsed for the submitted video by the R3D SDK to calculate the size of a heap buffer. Due to an integer overflow with regards to this calculation, this can result in an undersized heap buffer being allocated. When this heap buffer is written to, a heap-based buffer overflow will occur. This can result in code execution under the context of the application.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Integer overflow in Blackmagic Design","id":"CVE-2021-40417","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"integer_overflow","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Use after free in Blackmagic Design","id":"CVE-2021-40418"},"packages":[],"prev":{"headline":"Missing authorization in n/a","id":"CVE-2021-40416"},"products":["Blackmagic Design"],"published":"2021-12-22","related":[{"cvss_score":9.8,"headline":"Use after free in Blackmagic Design","id":"CVE-2021-40418","kev_date_added":null,"published":"2021-12-22"}],"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":"2024-08-04","vendors":["n/a"]},"summary":"An integer overflow in the DPDecoder service allows attackers to trigger a heap buffer overflow and execute arbitrary code via a crafted video file.","url":"https://insights.sbomify.com/CVE-2021-40417/"}
