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-2020-2320 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- unicorn (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-2020-2320/ (Markdown: https://insights.sbomify.com/OSV-2020-2320/index.md)","id":"OSV-2020-2320","markdown":"https://insights.sbomify.com/OSV-2020-2320/index.md","name":"OSV-2020-2320","record":{"aliases":[],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["code_execution","denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"QEMU ARM emulator","requires_auth":"none","summary":"A memory corruption vulnerability in QEMU's ARM emulator allows attackers to execute arbitrary code or cause denial of service.","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=20220\n\n```\nCrash type: UNKNOWN WRITE\nCrash state:\ncpu_arm_exec_arm\ntcg_exec_all_arm\nqemu_tcg_cpu_loop\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 cpu_arm_exec_arm","id":"OSV-2020-2320","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":"unicorn","purl":"pkg:generic/unicorn","source":"OSV-2020-2320"}],"products":null,"published":"2021-12-04","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 QEMU's ARM emulator allows attackers to execute arbitrary code or cause denial of service.","url":"https://insights.sbomify.com/OSV-2020-2320/"}
