An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2024-32621 in the wild and no public exploit code.\n\nAffected product: Hdfgroup Hdf5. 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-2024-32621/ (Markdown: https://insights.sbomify.com/CVE-2024-32621/index.md)","id":"CVE-2024-32621","markdown":"https://insights.sbomify.com/CVE-2024-32621/index.md","name":"CVE-2024-32621","record":{"aliases":["AZL-40561","AZL-40642","DEBIAN-CVE-2024-32621","ECHO-e887-dfa2-d508","GHSA-3mcf-4rgf-4fx9","JLSEC-2026-316","ROOT-OS-DEBIAN-11-CVE-2024-32621","ROOT-OS-DEBIAN-12-CVE-2024-32621","UBUNTU-CVE-2024-32621"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"HDF5 library","requires_auth":"none","summary":"A heap-based buffer overflow in the HDF5 library allows attackers to corrupt the instruction pointer, potentially leading to code execution or denial of service.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"hdf5","vendor":"hdfgroup"}],"cvss":{"score":9.8,"severity":"critical","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-122","name":"Heap-based Buffer Overflow"}],"description":"HDF5 Library through 1.14.3 contains a heap-based buffer overflow in H5HG_read in H5HG.c (called from H5VL__native_blob_get in H5VLnative_blob.c), resulting in the corruption of the instruction pointer.","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":"Memory corruption in n/a","id":"CVE-2024-32621","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"hdfgroup:hdf5","products":["hdfgroup:hdf5"],"type":"memory_corruption","year":"2024"},"n_packages":0,"n_references":1,"next":{"headline":"Memory corruption in n/a","id":"CVE-2024-32622"},"packages":[],"prev":{"headline":"Memory corruption in n/a","id":"CVE-2024-32620"},"products":["n/a"],"published":"2024-05-09","related":[{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2024-32608","kev_date_added":null,"published":"2024-10-09"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2024-29157","kev_date_added":null,"published":"2024-05-09"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2024-29159","kev_date_added":null,"published":"2024-05-09"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2024-29164","kev_date_added":null,"published":"2024-05-09"},{"cvss_score":9.8,"headline":"Other in n/a","id":"CVE-2024-32611","kev_date_added":null,"published":"2024-05-09"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2024-32615","kev_date_added":null,"published":"2024-05-09"}],"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":"yes","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2025-02-13","vendors":["n/a"]},"summary":"A heap-based buffer overflow in the HDF5 library allows attackers to corrupt the instruction pointer, potentially leading to code execution or denial of service.","url":"https://insights.sbomify.com/CVE-2024-32621/"}
