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-2023-281/ (Markdown: https://insights.sbomify.com/OSV-2023-281/index.md)","id":"OSV-2023-281","markdown":"https://insights.sbomify.com/OSV-2023-281/index.md","name":"OSV-2023-281","record":{"aliases":[],"analysis":{"component_type":"library","fix_type":"patch","impacts":["code_execution","denial_of_service"],"network_reachable":"unknown","non_default_config":false,"product_category":"UTF-8 conversion library","requires_auth":"none","summary":"A heap buffer overflow in simdutf allows attackers to cause denial of service or potentially execute code via crafted UTF-8 input.","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=57673\n\n```\nCrash type: Heap-buffer-overflow WRITE 16\nCrash state:\nunsigned long simdutf::haswell::convert_masked_utf8_to_utf16\u003c\nsimdutf::haswell::implementation::convert_utf8_to_utf16le\nroundtrip.cc\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":"Heap-buffer-overflow in unsigned long simdutf::haswell::convert_masked_utf8_to_utf16\u003c","id":"OSV-2023-281","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":"simdutf","purl":"pkg:generic/simdutf","source":"OSV-2023-281"}],"products":null,"published":"2023-04-05","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 heap buffer overflow in simdutf allows attackers to cause denial of service or potentially execute code via crafted UTF-8 input.","url":"https://insights.sbomify.com/OSV-2023-281/"}
