It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2022-46456 in the wild and no public exploit code.\n\nAffected product: Nasm Netwide Assembler. No package-level version data is available, so check the vendor advisory linked from the reference page.\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/CVE-2022-46456/ (Markdown: https://insights.sbomify.com/CVE-2022-46456/index.md)","id":"CVE-2022-46456","markdown":"https://insights.sbomify.com/CVE-2022-46456/index.md","name":"CVE-2022-46456","record":{"aliases":["AZL-12935","AZL-35024","DEBIAN-CVE-2022-46456","GHSA-cj3v-jx6q-7pw2","JLSEC-2026-204","UBUNTU-CVE-2022-46456"],"analysis":{"component_type":"developer_tool","fix_type":"upgrade","impacts":["code_execution","denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"NASM assembler","requires_auth":"none","summary":"A global buffer overflow in the NASM assembler allows attackers to execute arbitrary code or cause denial of service via crafted input.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"netwide_assembler","vendor":"nasm"}],"cvss":{"score":7.8,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-120","name":"Buffer Copy without Checking Size of Input"}],"description":"NASM v2.16 was discovered to contain a global buffer overflow in the component dbgdbg_typevalue at /output/outdbg.c.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Memory corruption in n/a","id":"CVE-2022-46456","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"nasm:netwide_assembler","products":["nasm:netwide_assembler"],"type":"memory_corruption","year":"2022"},"n_packages":0,"n_references":1,"next":{"headline":"Memory corruption in n/a","id":"CVE-2022-46457"},"packages":[],"prev":{"headline":"Memory corruption in n/a","id":"CVE-2022-46449"},"products":["n/a"],"published":"2023-01-04","related":[{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2004-1287","kev_date_added":null,"published":"2004-12-22"},{"cvss_score":9.8,"headline":"Use after free in n/a","id":"CVE-2020-24978","kev_date_added":null,"published":"2020-09-03"},{"cvss_score":9.3,"headline":"Memory corruption in n/a","id":"CVE-2008-7177","kev_date_added":null,"published":"2009-09-08"},{"cvss_score":7.8,"headline":"Memory corruption in n/a","id":"CVE-2023-31722","kev_date_added":null,"published":"2023-05-17"},{"cvss_score":7.8,"headline":"Memory corruption in n/a","id":"CVE-2022-44370","kev_date_added":null,"published":"2023-03-29"},{"cvss_score":7.8,"headline":"Use after free in n/a","id":"CVE-2019-8343","kev_date_added":null,"published":"2019-02-15"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2025-04-10","vendors":["n/a"]},"summary":"A global buffer overflow in the NASM assembler allows attackers to execute arbitrary code or cause denial of service via crafted input.","url":"https://insights.sbomify.com/CVE-2022-46456/"}
