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-2019-6291 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-2019-6291/ (Markdown: https://insights.sbomify.com/CVE-2019-6291/index.md)","id":"CVE-2019-6291","markdown":"https://insights.sbomify.com/CVE-2019-6291/index.md","name":"CVE-2019-6291","record":{"aliases":["DEBIAN-CVE-2019-6291","GHSA-mjrg-rf9g-9j6r","UBUNTU-CVE-2019-6291"],"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":"Remote attackers can cause denial of service in Netwide Assembler via crafted assembly files triggering stack exhaustion.","user_interaction":"required","vuln_class":"denial_of_service"},"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-674","name":"Uncontrolled Recursion"}],"description":"An issue was discovered in the function expr6 in eval.c in Netwide Assembler (NASM) through 2.14.02.
