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-2021-1061/ (Markdown: https://insights.sbomify.com/OSV-2021-1061/index.md)","id":"OSV-2021-1061","markdown":"https://insights.sbomify.com/OSV-2021-1061/index.md","name":"OSV-2021-1061","record":{"aliases":[],"analysis":{"component_type":"library","fix_type":"no_fix_stated","impacts":["code_execution","denial_of_service"],"network_reachable":"unknown","non_default_config":false,"product_category":"OSS-Fuzz library","requires_auth":"unknown","summary":"An unknown write vulnerability in CompileBlock can lead to memory corruption, potentially allowing code execution or denial of service.","user_interaction":"unknown","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=36551\n\n```\nCrash type: UNKNOWN WRITE\nCrash state:\nCompileBlock\nCompileElseBlock\nCompile_If\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 CompileBlock","id":"OSV-2021-1061","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":"wasm3","purl":"pkg:generic/wasm3","source":"OSV-2021-1061"}],"products":null,"published":"2021-07-26","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":"An unknown write vulnerability in CompileBlock can lead to memory corruption, potentially allowing code execution or denial of service.","url":"https://insights.sbomify.com/OSV-2021-1061/"}
