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 OSV-2021-441 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- sudoers (OSS-Fuzz): affected all versions; no fix listed\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/OSV-2021-441/ (Markdown: https://insights.sbomify.com/OSV-2021-441/index.md)","id":"OSV-2021-441","markdown":"https://insights.sbomify.com/OSV-2021-441/index.md","name":"OSV-2021-441","record":{"aliases":[],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["code_execution","privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"sudoers library","requires_auth":"none","summary":"A memory corruption vulnerability in sudoers_lookup_check allows local attackers to potentially execute arbitrary code or escalate privileges.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"OSS-Fuzz report: https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=31250\n\n```\nCrash type: UNKNOWN WRITE\nCrash state:\nsudoers_lookup_check\nsudoers_lookup\nfuzz_sudoers.c\n```","ecosystems":["OSS-Fuzz"],"exploits":{"exploitdb":null,"first_seen":null,"github_poc":null,"max_poc_stars":null,"metasploit":null,"nuclei":null,"refs":[],"tier":null},"has_fix":false,"headline":"UNKNOWN WRITE in sudoers_lookup_check","id":"OSV-2021-441","indexable":true,"kev":null,"kind":"advisory","links":{"ecosystem":"OSS-Fuzz","product":null,"products":[],"type":"memory_corruption","year":"2021"},"n_packages":1,"n_references":null,"packages":[{"ecosystem":"OSS-Fuzz","fixed":[],"introduced":[],"last_affected":[],"package":"sudoers","purl":"pkg:generic/sudoers","source":"OSV-2021-441"}],"products":null,"published":"2021-02-24","related":[],"sources":[{"class":"attribution","licence":"CC BY 4.0","name":"OSS-Fuzz","prefix":"OSV"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":null,"updated":null,"vendors":null},"summary":"A memory corruption vulnerability in sudoers_lookup_check allows local attackers to potentially execute arbitrary code or escalate privileges.","url":"https://insights.sbomify.com/OSV-2021-441/"}
