It can be exploited over the network, with no action from the victim.\nExploitation: There is no known exploitation of OSV-2022-1276 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- openvpn (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-2022-1276/ (Markdown: https://insights.sbomify.com/OSV-2022-1276/index.md)","id":"OSV-2022-1276","markdown":"https://insights.sbomify.com/OSV-2022-1276/index.md","name":"OSV-2022-1276","record":{"aliases":[],"analysis":{"component_type":"library","fix_type":"patch","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"NTLM authentication library","requires_auth":"unknown","summary":"A stack buffer overflow in the NTLM phase 3 function allows attackers to cause crashes or potentially execute code via crafted proxy authentication data.","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=59818\n\n```\nCrash type: Stack-buffer-overflow WRITE 1\nCrash state:\nntlm_phase_3\nestablish_http_proxy_passthru\nfuzz_proxy.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":"Stack-buffer-overflow in ntlm_phase_3","id":"OSV-2022-1276","indexable":true,"kev":null,"kind":"advisory","links":{"ecosystem":"OSS-Fuzz","product":null,"products":[],"type":"memory_corruption","year":"2023"},"n_packages":1,"n_references":null,"packages":[{"ecosystem":"OSS-Fuzz","fixed":[],"introduced":[],"last_affected":[],"package":"openvpn","purl":"pkg:generic/openvpn","source":"OSV-2022-1276"}],"products":null,"published":"2023-06-15","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 stack buffer overflow in the NTLM phase 3 function allows attackers to cause crashes or potentially execute code via crafted proxy authentication data.","url":"https://insights.sbomify.com/OSV-2022-1276/"}
