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-2021-30199 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-2021-30199/ (Markdown: https://insights.sbomify.com/CVE-2021-30199/index.md)","id":"CVE-2021-30199","markdown":"https://insights.sbomify.com/CVE-2021-30199/index.md","name":"CVE-2021-30199","record":{"aliases":["DEBIAN-CVE-2021-30199","GHSA-xr38-33h6-9m6r","UBUNTU-CVE-2021-30199"],"analysis":{"component_type":"library","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"GPAC multimedia library","requires_auth":"none","summary":"A crafted MP4 file causes a null pointer dereference in GPAC, leading to a crash and denial of service.","user_interaction":"required","vuln_class":"null_dereference"},"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:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-476","name":"NULL Pointer Dereference"}],"description":"In filters/reframe_latm.c in GPAC 1.0.1 there is a Null Pointer Dereference, when gf_filter_pck_get_data is called.
