An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2023-37365 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- hnswlib (PyPI): affected all versions; fixed in 0.8.0\n- hnswlib (PyPI): affected all versions; fixed in 0.8.0\n- hnswlib (PyPI): affected all versions; fixed in 0.8.0\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-2023-37365/ (Markdown: https://insights.sbomify.com/CVE-2023-37365/index.md)","id":"CVE-2023-37365","markdown":"https://insights.sbomify.com/CVE-2023-37365/index.md","name":"CVE-2023-37365","record":{"aliases":["DEBIAN-CVE-2023-37365","GHSA-xwc8-rf6m-xr86","PYSEC-2026-1450","UBUNTU-CVE-2023-37365"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service","code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Hnswlib library","requires_auth":"none","summary":"A double free vulnerability in Hnswlib allows attackers to cause denial of service or potentially execute code via a large M argument.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"hnswlib","vendor":"hnswlib_project"}],"cvss":{"score":6.5,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-415","name":"Double Free"}],"description":"Hnswlib 0.7.0 has a double free in init_index when the M argument is a large integer.","ecosystems":["PyPI"],"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":"hnswlib Double Free vulnerability","id":"CVE-2023-37365","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"PyPI","product":null,"products":[],"type":"memory_corruption","year":"2023"},"n_packages":3,"n_references":1,"next":{"headline":"Denial of service in Exynos 850 firmware","id":"CVE-2023-37366"},"packages":[{"ecosystem":"PyPI","fixed":["0.8.0"],"introduced":["0"],"last_affected":[],"package":"hnswlib","purl":null,"source":"GHSA-xwc8-rf6m-xr86"},{"ecosystem":"PyPI","fixed":["0.8.0"],"introduced":["0"],"last_affected":[],"package":"hnswlib","purl":"pkg:pypi/hnswlib","source":"GHSA-xwc8-rf6m-xr86"},{"ecosystem":"PyPI","fixed":["0.8.0"],"introduced":["0"],"last_affected":[],"package":"hnswlib","purl":"pkg:pypi/hnswlib","source":"PYSEC-2026-1450"}],"prev":{"headline":"XML external entity in n/a","id":"CVE-2023-37364"},"products":["n/a"],"published":"2023-06-30","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"class":"attribution","licence":"CC BY 4.0","name":"PyPA Advisory Database","prefix":"PYSEC"},{"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":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2024-12-05","vendors":["n/a"]},"summary":"A double free vulnerability in Hnswlib allows attackers to cause denial of service or potentially execute code via a large M argument.","url":"https://insights.sbomify.com/CVE-2023-37365/"}
