It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-45928 in the wild and no public exploit code.\n\nAffected product: n/a. 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-2021-45928/ (Markdown: https://insights.sbomify.com/CVE-2021-45928/index.md)","id":"CVE-2021-45928","markdown":"https://insights.sbomify.com/CVE-2021-45928/index.md","name":"CVE-2021-45928","record":{"aliases":["GHSA-4m3c-5mq3-5qxq"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution","denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"JPEG XL library","requires_auth":"low_privilege","summary":"An out-of-bounds write in libjxl allows attackers to execute arbitrary code or cause denial of service via crafted images.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"libjxl","vendor":"libjxl_project"}],"cvss":{"score":5.5,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"}],"description":"libjxl b02d6b9, as used in libvips 8.11 through 8.11.2 and other products, has an out-of-bounds write in jxl::ModularFrameDecoder::DecodeGroup (called from jxl::FrameDecoder::ProcessACGroup and jxl::ThreadPool::RunCallState\u003cjxl::FrameDecoder::ProcessSections).","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"Memory corruption in n/a","id":"CVE-2021-45928","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2021"},"n_packages":0,"n_references":5,"next":{"headline":"Memory corruption in n/a","id":"CVE-2021-45929"},"packages":[],"prev":{"headline":"Memory corruption in n/a","id":"CVE-2021-45927"},"products":["n/a"],"published":"2021-12-31","related":[{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2021-27804","kev_date_added":null,"published":"2021-03-02"},{"cvss_score":8.7,"headline":"libjxl: Out-of-bounds write in grayscale color transformation when using LCMS2","id":"CVE-2026-1837","kev_date_added":null,"published":"2026-02-11"},{"cvss_score":7.5,"headline":"Integer overflow in n/a","id":"CVE-2023-35790","kev_date_added":null,"published":"2023-06-16"},{"cvss_score":7.5,"headline":"Denial of service in n/a","id":"CVE-2021-36691","kev_date_added":null,"published":"2021-08-30"},{"cvss_score":6.9,"headline":"Out of Bounds Memory Read/Write in libjxl","id":"CVE-2024-11403","kev_date_added":null,"published":"2024-11-25"},{"cvss_score":6.9,"headline":"Resource exhaustion via Stack overflow in libjxl","id":"CVE-2024-11498","kev_date_added":null,"published":"2024-11-25"},{"cvss_score":6.5,"headline":"Denial of service in n/a","id":"CVE-2022-34000","kev_date_added":null,"published":"2022-06-19"}],"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 out-of-bounds write in libjxl allows attackers to execute arbitrary code or cause denial of service via crafted images.","url":"https://insights.sbomify.com/CVE-2021-45928/"}
