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-2021-40571 in the wild and no public exploit code.\n\nAffected product: Gpac Gpac. 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-2021-40571/ (Markdown: https://insights.sbomify.com/CVE-2021-40571/index.md)","id":"CVE-2021-40571","markdown":"https://insights.sbomify.com/CVE-2021-40571/index.md","name":"CVE-2021-40571","record":{"aliases":["DEBIAN-CVE-2021-40571","GHSA-xjv4-5hjm-mw83","UBUNTU-CVE-2021-40571"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution","privilege_escalation","denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"GPAC MP4Box","requires_auth":"none","summary":"A double-free vulnerability in GPAC's MP4Box allows attackers to execute arbitrary code, escalate privileges, or cause denial of service.","user_interaction":"required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"gpac","vendor":"gpac"}],"cvss":{"score":7.8,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-415","name":"Double Free"}],"description":"The binary MP4Box in Gpac 1.0.1 has a double-free vulnerability in the ilst_box_read function in box_code_apple.c, which allows attackers to cause a denial of service, even code execution and escalation of privileges.","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":"Use after free in n/a","id":"CVE-2021-40571","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"gpac:gpac","products":["gpac:gpac"],"type":"use_after_free","year":"2021"},"n_packages":0,"n_references":3,"next":{"headline":"Memory corruption in n/a","id":"CVE-2021-40572"},"packages":[],"prev":{"headline":"Use after free in n/a","id":"CVE-2021-40570"},"products":["n/a"],"published":"2022-01-13","related":[{"cvss_score":9.8,"headline":"Null dereference in n/a","id":"CVE-2023-46427","kev_date_added":null,"published":"2024-03-09"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2023-46932","kev_date_added":null,"published":"2023-12-09"},{"cvss_score":9.8,"headline":"Use after free in n/a","id":"CVE-2022-36190","kev_date_added":null,"published":"2022-08-17"},{"cvss_score":9.8,"headline":"Null dereference in n/a","id":"CVE-2021-28300","kev_date_added":null,"published":"2021-04-14"},{"cvss_score":9.8,"headline":"Use after free in n/a","id":"CVE-2020-11558","kev_date_added":null,"published":"2020-04-05"},{"cvss_score":9.1,"headline":"Memory corruption in n/a","id":"CVE-2020-19751","kev_date_added":null,"published":"2021-09-07"},{"cvss_score":8.8,"headline":"Memory corruption in n/a","id":"CVE-2023-46426","kev_date_added":null,"published":"2024-03-09"}],"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":"A double-free vulnerability in GPAC's MP4Box allows attackers to execute arbitrary code, escalate privileges, or cause denial of service.","url":"https://insights.sbomify.com/CVE-2021-40571/"}
