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-2021-45263 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-2021-45263/ (Markdown: https://insights.sbomify.com/CVE-2021-45263/index.md)","id":"CVE-2021-45263","markdown":"https://insights.sbomify.com/CVE-2021-45263/index.md","name":"CVE-2021-45263","record":{"aliases":["DEBIAN-CVE-2021-45263","GHSA-fvx8-gwc7-qjhw","UBUNTU-CVE-2021-45263"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"GPAC multimedia library","requires_auth":"none","summary":"An attacker can cause a denial of service via a segmentation fault in the GPAC library's SVG attribute handling.","user_interaction":"required","vuln_class":"use_after_free"},"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-416","name":"Use After Free"}],"description":"An invalid free vulnerability exists in gpac 1.1.0 via the gf_svg_delete_attribute_value function, which causes a segmentation fault and application crash.","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-2021-45263","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":2,"next":{"headline":"Null dereference in n/a","id":"CVE-2021-45266"},"packages":[],"prev":{"headline":"Use after free in n/a","id":"CVE-2021-45262"},"products":["n/a"],"published":"2021-12-22","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":"An attacker can cause a denial of service via a segmentation fault in the GPAC library's SVG attribute handling.","url":"https://insights.sbomify.com/CVE-2021-45263/"}
