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-2020-36221 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- openldap (Bitnami): affected all versions; fixed in 2.4.57\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-2020-36221/ (Markdown: https://insights.sbomify.com/CVE-2020-36221/index.md)","id":"CVE-2020-36221","markdown":"https://insights.sbomify.com/CVE-2020-36221/index.md","name":"CVE-2020-36221","record":{"aliases":["ALPINE-CVE-2020-36221","BIT-openldap-2020-36221","CLEANSTART-2026-HK58158","DEBIAN-CVE-2020-36221","GHSA-xm66-m73v-859r","JLSEC-2026-163","UBUNTU-CVE-2020-36221"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"OpenLDAP server","requires_auth":"none","summary":"An integer underflow in OpenLDAP's Certificate Exact Assertion processing allows attackers to crash the slapd service, causing denial of service.","user_interaction":"not_required","vuln_class":"integer_overflow"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"mac_os_x","vendor":"apple"},{"product":"macos","vendor":"apple"},{"product":"debian_linux","vendor":"debian"},{"product":"openldap","vendor":"openldap"}],"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-191","name":"Integer Underflow (Wrap or Wraparound)"}],"description":"An integer underflow was discovered in OpenLDAP before 2.4.57 leading to slapd crashes in the Certificate Exact Assertion processing, resulting in denial of service (schema_init.c serialNumberAndIssuerCheck).","ecosystems":["Bitnami"],"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":"Integer overflow in n/a","id":"CVE-2020-36221","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Bitnami","product":"apple:mac_os_x","products":["apple:mac_os_x","apple:macos","debian:debian_linux","openldap:openldap"],"type":"integer_overflow","year":"2020"},"n_packages":1,"n_references":16,"next":{"headline":"Denial of service in n/a","id":"CVE-2020-36222"},"packages":[{"ecosystem":"Bitnami","fixed":["2.4.57"],"introduced":["0"],"last_affected":[],"package":"openldap","purl":"pkg:bitnami/openldap","source":"BIT-openldap-2020-36221"}],"prev":{"headline":"Data race in va-ts","id":"CVE-2020-36220"},"products":["n/a"],"published":"2021-01-25","related":[{"cvss_score":9.8,"headline":"GNU Bourne-Again Shell (Bash) Arbitrary Code Execution","id":"CVE-2014-7169","kev_date_added":"2022-01-28","published":"2014-09-25"},{"cvss_score":9.8,"headline":"GNU Bourne-Again Shell (Bash) Arbitrary Code Execution","id":"CVE-2014-6271","kev_date_added":"2022-01-28","published":"2014-09-24"},{"cvss_score":9.8,"headline":"PHP-CGI Query String Parameter","id":"CVE-2012-1823","kev_date_added":"2022-03-25","published":"2012-05-11"},{"cvss_score":7.8,"headline":"Apple macOS Unspecified","id":"CVE-2021-30713","kev_date_added":"2021-11-03","published":"2021-09-08"},{"cvss_score":7.8,"headline":"Apple macOS Use-After-Free","id":"CVE-2019-8526","kev_date_added":"2023-04-17","published":"2019-12-18"},{"cvss_score":7.8,"headline":"Apple OS X Authentication Bypass","id":"CVE-2015-1130","kev_date_added":"2022-02-10","published":"2015-04-10"},{"cvss_score":5.5,"headline":"Apple macOS Out-of-Bounds Read","id":"CVE-2022-22674","kev_date_added":"2022-04-04","published":"2022-05-26"}],"sources":[{"class":"attribution","licence":"Apache-2.0","name":"Bitnami","prefix":"BIT"},{"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":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2026-10-14","vendors":["n/a"]},"summary":"An integer underflow in OpenLDAP's Certificate Exact Assertion processing allows attackers to crash the slapd service, causing denial of service.","url":"https://insights.sbomify.com/CVE-2020-36221/"}
