It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2020-15945 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- lua (Bitnami): affected from 5.3.1; fixed in 5.4.0\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-2020-15945/ (Markdown: https://insights.sbomify.com/CVE-2020-15945/index.md)","id":"CVE-2020-15945","markdown":"https://insights.sbomify.com/CVE-2020-15945/index.md","name":"CVE-2020-15945","record":{"aliases":["AZL-40818","AZL-6671","BIT-lua-2020-15945","DEBIAN-CVE-2020-15945","GHSA-4fp8-99qh-27p3","JLSEC-2026-554","MINI-mrqg-mw4v-pqqc"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Lua scripting library","requires_auth":"low_privilege","summary":"A segmentation fault in Lua's debug module allows attackers to cause a denial of service via crafted scripts.","user_interaction":"not_required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"lua","vendor":"lua"}],"cvss":{"score":5.5,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[],"description":"Lua 5.4.0 (fixed in 5.4.1) has a segmentation fault in changedline in ldebug.c (e.g., when called by luaG_traceexec) because it incorrectly expects that an oldpc value is always updated upon a return of the flow of control to a function.","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":"Null dereference in n/a","id":"CVE-2020-15945","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Bitnami","product":null,"products":[],"type":"null_dereference","year":"2020"},"n_packages":1,"n_references":3,"next":{"headline":"SQL injection in n/a","id":"CVE-2020-15947"},"packages":[{"ecosystem":"Bitnami","fixed":["5.4.0"],"introduced":["5.3.1"],"last_affected":[],"package":"lua","purl":"pkg:bitnami/lua","source":"BIT-lua-2020-15945"}],"prev":{"headline":"Cross-site scripting in n/a","id":"CVE-2020-15944"},"products":["n/a"],"published":"2020-07-24","related":[{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2020-15889","kev_date_added":null,"published":"2020-07-21"},{"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":5.3,"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":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2025-02-19","vendors":["n/a"]},"summary":"A segmentation fault in Lua's debug module allows attackers to cause a denial of service via crafted scripts.","url":"https://insights.sbomify.com/CVE-2020-15945/"}
