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-2018-19755 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-2018-19755/ (Markdown: https://insights.sbomify.com/CVE-2018-19755/index.md)","id":"CVE-2018-19755","markdown":"https://insights.sbomify.com/CVE-2018-19755/index.md","name":"CVE-2018-19755","record":{"aliases":["DEBIAN-CVE-2018-19755","GHSA-cvx6-2fc8-p5cg","UBUNTU-CVE-2018-19755"],"analysis":{"component_type":"developer_tool","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Netwide Assembler","requires_auth":"none","summary":"An integer overflow in NASM's preprocessor leads to an out-of-bounds array access, causing a denial of service when processing malicious assembly files.","user_interaction":"required","vuln_class":"integer_overflow"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"netwide_assembler","vendor":"nasm"}],"cvss":{"score":5.5,"severity":"medium","source":"nvd","vector":"CVSS:3.0/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H","version":"3.0"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"}],"description":"There is an illegal address access at asm/preproc.c (function: is_mmacro) in Netwide Assembler (NASM) 2.14rc16 that will cause a denial of service (out-of-bounds array access) because a certain conversion can result in a negative integer.","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":"Integer overflow in n/a","id":"CVE-2018-19755","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"nasm:netwide_assembler","products":["nasm:netwide_assembler"],"type":"integer_overflow","year":"2018"},"n_packages":0,"n_references":2,"next":{"headline":"Memory corruption in n/a","id":"CVE-2018-19756"},"packages":[],"prev":{"headline":"Missing authorization in n/a","id":"CVE-2018-19754"},"products":["n/a"],"published":"2018-11-30","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":"Memory corruption in n/a","id":"CVE-2022-46456","kev_date_added":null,"published":"2023-01-04"},{"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":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-09-16","vendors":["n/a"]},"summary":"An integer overflow in NASM's preprocessor leads to an out-of-bounds array access, causing a denial of service when processing malicious assembly files.","url":"https://insights.sbomify.com/CVE-2018-19755/"}
