It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2020-36401 in the wild and no public exploit code.\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-2020-36401/ (Markdown: https://insights.sbomify.com/CVE-2020-36401/index.md)","id":"CVE-2020-36401","markdown":"https://insights.sbomify.com/CVE-2020-36401/index.md","name":"CVE-2020-36401","record":{"aliases":["DEBIAN-CVE-2020-36401","GHSA-qq64-7fh7-7hmw","UBUNTU-CVE-2020-36401"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution","denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"mruby library","requires_auth":"none","summary":"A double free vulnerability in mruby allows attackers to cause denial of service or potentially execute arbitrary code.","user_interaction":"required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"mruby","vendor":"mruby"}],"cvss":{"score":7.8,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-415","name":"Double Free"}],"description":"mruby 2.1.2 has a double free in mrb_default_allocf (called from mrb_free and obj_free).","ecosystems":[],"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":"Use after free in n/a","id":"CVE-2020-36401","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"use_after_free","year":"2020"},"n_packages":0,"n_references":3,"next":{"headline":"Use after free in n/a","id":"CVE-2020-36402"},"packages":[],"prev":{"headline":"Memory corruption in n/a","id":"CVE-2020-36400"},"products":["n/a"],"published":"2021-07-01","related":[{"cvss_score":9.8,"headline":"Use after free in n/a","id":"CVE-2020-6838","kev_date_added":null,"published":"2020-01-11"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2020-6839","kev_date_added":null,"published":"2020-01-11"},{"cvss_score":9.8,"headline":"Use after free in n/a","id":"CVE-2020-6840","kev_date_added":null,"published":"2020-01-11"},{"cvss_score":9.8,"headline":"Use after free in n/a","id":"CVE-2018-10199","kev_date_added":null,"published":"2018-04-18"},{"cvss_score":9.3,"headline":"Use-After-Free in str_escape in mruby/mruby in mruby/mruby","id":"CVE-2022-1212","kev_date_added":null,"published":"2022-04-05"},{"cvss_score":9.1,"headline":"NULL Pointer Dereference in mruby/mruby","id":"CVE-2021-4110","kev_date_added":null,"published":"2021-12-15"},{"cvss_score":8.4,"headline":"Out-of-bounds Read in mrb_get_args in mruby/mruby","id":"CVE-2022-1276","kev_date_added":null,"published":"2022-04-10"}],"sources":[{"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":"2024-08-04","vendors":["n/a"]},"summary":"A double free vulnerability in mruby allows attackers to cause denial of service or potentially execute arbitrary code.","url":"https://insights.sbomify.com/CVE-2020-36401/"}
