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-2020-15889 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- lua (Bitnami): affected from 5.4.0; fixed in 5.4.1\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-2020-15889/ (Markdown: https://insights.sbomify.com/CVE-2020-15889/index.md)","id":"CVE-2020-15889","markdown":"https://insights.sbomify.com/CVE-2020-15889/index.md","name":"CVE-2020-15889","record":{"aliases":["BIT-lua-2020-15889","DEBIAN-CVE-2020-15889","GHSA-j29r-h8wr-v5v8"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service","data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Lua programming language","requires_auth":"none","summary":"A heap-based buffer over-read in Lua's garbage collector allows attackers to cause denial of service or disclose sensitive memory contents.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"lua","vendor":"lua"}],"cvss":{"score":9.8,"severity":"critical","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-125","name":"Out-of-bounds Read"}],"description":"Lua 5.4.0 has a getobjname heap-based buffer over-read because youngcollection in lgc.c uses markold for an insufficient number of list members.","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":"Memory corruption in n/a","id":"CVE-2020-15889","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Bitnami","product":null,"products":[],"type":"memory_corruption","year":"2020"},"n_packages":1,"n_references":3,"next":{"headline":"Memory corruption in n/a","id":"CVE-2020-15890"},"packages":[{"ecosystem":"Bitnami","fixed":["5.4.1"],"introduced":["5.4.0"],"last_affected":[],"package":"lua","purl":"pkg:bitnami/lua","source":"BIT-lua-2020-15889"}],"prev":{"headline":"Use after free in n/a","id":"CVE-2020-15888"},"products":["n/a"],"published":"2020-07-21","related":[{"cvss_score":8.8,"headline":"Use after free in n/a","id":"CVE-2020-15888","kev_date_added":null,"published":"2020-07-21"},{"cvss_score":7.5,"headline":"Memory corruption in n/a","id":"CVE-2021-45985","kev_date_added":null,"published":"2023-04-10"},{"cvss_score":7.5,"headline":"Null dereference in n/a","id":"CVE-2020-24369","kev_date_added":null,"published":"2020-08-17"},{"cvss_score":6.3,"headline":"Use after free in n/a","id":"CVE-2021-44964","kev_date_added":null,"published":"2022-03-14"},{"cvss_score":5.5,"headline":"Null dereference in n/a","id":"CVE-2020-15945","kev_date_added":null,"published":"2020-07-24"},{"cvss_score":5.3,"headline":"Memory corruption in n/a","id":"CVE-2020-24371","kev_date_added":null,"published":"2020-08-17"}],"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":"2024-08-04","vendors":["n/a"]},"summary":"A heap-based buffer over-read in Lua's garbage collector allows attackers to cause denial of service or disclose sensitive memory contents.","url":"https://insights.sbomify.com/CVE-2020-15889/"}
