It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2025-6270 exists.\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-2025-6270/ (Markdown: https://insights.sbomify.com/CVE-2025-6270/index.md)","id":"CVE-2025-6270","markdown":"https://insights.sbomify.com/CVE-2025-6270/index.md","name":"CVE-2025-6270","record":{"aliases":["DEBIAN-CVE-2025-6270","ECHO-2c29-b307-44bb","GHSA-5pmf-w3jq-5hrj","JLSEC-2026-340","UBUNTU-CVE-2025-6270"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution","denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"HDF5 library","requires_auth":"low_privilege","summary":"A heap-based buffer overflow in HDF5 allows local attackers to execute arbitrary code or cause denial of service via crafted files.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulDB","cpe":[{"product":"hdf5","vendor":"hdfgroup"}],"cvss":{"score":4.8,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N/E:P","version":"4.0"},"cwes":[{"id":"CWE-122","name":"Heap-based Buffer Overflow"},{"id":"CWE-119","name":"Improper Restriction of Operations within the Bounds of a Memory Buffer"}],"description":"A vulnerability, which was classified as critical, has been found in HDF5 up to 1.14.6.
