Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2025-29476 exists.\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-2025-29476/ (Markdown: https://insights.sbomify.com/CVE-2025-29476/index.md)","id":"CVE-2025-29476","markdown":"https://insights.sbomify.com/CVE-2025-29476/index.md","name":"CVE-2025-29476","record":{"aliases":["DEBIAN-CVE-2025-29476","GHSA-p53h-9vwh-rvvp","UBUNTU-CVE-2025-29476"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"C-Blosc2 compression library","requires_auth":"low_privilege","summary":"A buffer overflow in the C-Blosc2 library allows attackers to execute arbitrary code or cause denial of service via crafted compressed data.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[],"cvss":{"score":5.5,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:U/C:L/I:L/A:L","version":"3.1"},"cwes":[{"id":"CWE-120","name":"Buffer Copy without Checking Size of Input"}],"description":"Buffer Overflow vulnerability in compress_chunk_fuzzer with oss-fuzz on commit 16450518afddcb3139de627157208e49bfef6987 in c-blosc2 v.2.17.0 and before.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":true,"headline":"Memory corruption in n/a","id":"CVE-2025-29476","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2025"},"n_packages":0,"n_references":2,"next":{"headline":"Denial of service in n/a","id":"CVE-2025-29477"},"packages":[],"prev":{"headline":"Cross-site scripting in n/a","id":"CVE-2025-29471"},"products":["n/a"],"published":"2025-04-04","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-04-07","vendors":["n/a"]},"summary":"A buffer overflow in the C-Blosc2 library allows attackers to execute arbitrary code or cause denial of service via crafted compressed data.","url":"https://insights.sbomify.com/CVE-2025-29476/"}
