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-2021-31261 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-2021-31261/ (Markdown: https://insights.sbomify.com/CVE-2021-31261/index.md)","id":"CVE-2021-31261","markdown":"https://insights.sbomify.com/CVE-2021-31261/index.md","name":"CVE-2021-31261","record":{"aliases":["DEBIAN-CVE-2021-31261","GHSA-6ff2-p962-67wg","UBUNTU-CVE-2021-31261"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"GPAC multimedia library","requires_auth":"none","summary":"Attackers can read memory via a crafted file in MP4Box, potentially exposing sensitive data from the GPAC multimedia library.","user_interaction":"required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"gpac","vendor":"gpac"}],"cvss":{"score":5.5,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-119","name":"Improper Restriction of Operations within the Bounds of a Memory Buffer"}],"description":"The gf_hinter_track_new function in GPAC 1.0.1 allows attackers to read memory via a crafted file in the MP4Box command.","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":"Information disclosure in n/a","id":"CVE-2021-31261","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"gpac:gpac","products":["gpac:gpac"],"type":"information_disclosure","year":"2021"},"n_packages":0,"n_references":2,"next":{"headline":"Null dereference in n/a","id":"CVE-2021-31262"},"packages":[],"prev":{"headline":"Null dereference in n/a","id":"CVE-2021-31260"},"products":["n/a"],"published":"2021-04-19","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":"2024-08-03","vendors":["n/a"]},"summary":"Attackers can read memory via a crafted file in MP4Box, potentially exposing sensitive data from the GPAC multimedia library.","url":"https://insights.sbomify.com/CVE-2021-31261/"}
