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-2021-41497 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- bounter (PyPI): affected all versions up to 1.2.0; no fix listed\n- bounter (PyPI): affected all versions up to 1.2.0; no fix listed\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-2021-41497/ (Markdown: https://insights.sbomify.com/CVE-2021-41497/index.md)","id":"CVE-2021-41497","markdown":"https://insights.sbomify.com/CVE-2021-41497/index.md","name":"CVE-2021-41497","record":{"aliases":["GHSA-74xw-gwfm-7pv7"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Python hash library","requires_auth":"none","summary":"Attackers can cause a denial of service in the bounter library by inputting a huge hash bucket width, triggering a null pointer dereference.","user_interaction":"not_required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"bounter","vendor":"rare-technologies"}],"cvss":{"score":7.5,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-476","name":"NULL Pointer Dereference"}],"description":"Null pointer reference in CMS_Conservative_increment_obj in RaRe-Technologies bounter version 1.01 and 1.10, allows attackers to conduct Denial of Service attacks by inputting a huge width of hash bucket.","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":false,"headline":"bounter Null pointer reference","id":"CVE-2021-41497","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"PyPI","product":null,"products":[],"type":"null_dereference","year":"2021"},"n_packages":2,"n_references":1,"next":{"headline":"Pyo Buffer Overflow Vulnerability","id":"CVE-2021-41498"},"packages":[{"ecosystem":"PyPI","fixed":[],"introduced":["0"],"last_affected":["1.2.0"],"package":"bounter","purl":null,"source":"GHSA-74xw-gwfm-7pv7"},{"ecosystem":"PyPI","fixed":[],"introduced":["0"],"last_affected":["1.2.0"],"package":"bounter","purl":"pkg:pypi/bounter","source":"GHSA-74xw-gwfm-7pv7"}],"prev":{"headline":"Buffer Copy without Checking Size of Input in NumPy","id":"CVE-2021-41496"},"products":["n/a"],"published":"2021-12-17","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":"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":"Attackers can cause a denial of service in the bounter library by inputting a huge hash bucket width, triggering a null pointer dereference.","url":"https://insights.sbomify.com/CVE-2021-41497/"}
