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-2021-44964 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- lua (Bitnami): affected from 5.4.0; fixed in 5.4.4\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-2021-44964/ (Markdown: https://insights.sbomify.com/CVE-2021-44964/index.md)","id":"CVE-2021-44964","markdown":"https://insights.sbomify.com/CVE-2021-44964/index.md","name":"CVE-2021-44964","record":{"aliases":["AZL-40979","AZL-60034","AZL-60112","AZL-9048","BIT-lua-2021-44964","DEBIAN-CVE-2021-44964","GHSA-rvj2-9p3c-wmwh","JLSEC-2026-558","OESA-2022-1860","UBUNTU-CVE-2021-44964"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution","security_bypass"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Lua interpreter","requires_auth":"none","summary":"Attackers can execute arbitrary code and escape the sandbox by exploiting a use-after-free vulnerability in the Lua interpreter's garbage collector.","user_interaction":"required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"lua","vendor":"lua"}],"cvss":{"score":6.3,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:C/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-416","name":"Use After Free"}],"description":"Use after free in garbage collector and finalizer of lgc.c in Lua interpreter 5.4.0~5.4.3 allows attackers to perform Sandbox Escape via a crafted script file.","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":"Use after free in n/a","id":"CVE-2021-44964","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Bitnami","product":null,"products":[],"type":"use_after_free","year":"2021"},"n_packages":1,"n_references":5,"next":{"headline":"Path traversal in n/a","id":"CVE-2021-44965"},"packages":[{"ecosystem":"Bitnami","fixed":["5.4.4"],"introduced":["5.4.0"],"last_affected":[],"package":"lua","purl":"pkg:bitnami/lua","source":"BIT-lua-2021-44964"}],"prev":{"headline":"Information disclosure in n/a","id":"CVE-2021-44962"},"products":["n/a"],"published":"2022-03-14","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":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":"Attackers can execute arbitrary code and escape the sandbox by exploiting a use-after-free vulnerability in the Lua interpreter's garbage collector.","url":"https://insights.sbomify.com/CVE-2021-44964/"}
