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: It is not confirmed as exploited in the wild, but public exploit code for CVE-2023-49558 exists.\n\nAffected product: n/a. 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-2023-49558/ (Markdown: https://insights.sbomify.com/CVE-2023-49558/index.md)","id":"CVE-2023-49558","markdown":"https://insights.sbomify.com/CVE-2023-49558/index.md","name":"CVE-2023-49558","record":{"aliases":["AZL-33358","AZL-35386","DEBIAN-CVE-2023-49558","GHSA-w3p5-6w9w-p383","UBUNTU-CVE-2023-49558"],"analysis":{"component_type":"developer_tool","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"YASM assembler","requires_auth":"none","summary":"A remote attacker can cause a denial of service in the YASM assembler via the expand_mmac_params function.","user_interaction":"required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"yasm","vendor":"yasm_project"}],"cvss":{"score":5.5,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[],"description":"An issue in YASM 1.3.0.86.g9def allows a remote attacker to cause a denial of service via the expand_mmac_params function in the modules/preprocs/nasm/nasm-pp.c component.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":false,"headline":"Denial of service in n/a","id":"CVE-2023-49558","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2023"},"n_packages":0,"n_references":1,"next":{"headline":"gqlparser denial of service vulnerability via the parserDirectives function","id":"CVE-2023-49559"},"packages":[],"prev":{"headline":"Denial of service in n/a","id":"CVE-2023-49557"},"products":["n/a"],"published":"2024-01-02","related":[{"cvss_score":7.8,"headline":"Null dereference in n/a","id":"CVE-2023-31724","kev_date_added":null,"published":"2023-05-17"},{"cvss_score":6.2,"headline":"Memory corruption in n/a","id":"CVE-2023-29583","kev_date_added":null,"published":"2023-04-24"},{"cvss_score":5.5,"headline":"Use after free in n/a","id":"CVE-2023-49554","kev_date_added":null,"published":"2024-01-02"},{"cvss_score":5.5,"headline":"Denial of service in n/a","id":"CVE-2023-49555","kev_date_added":null,"published":"2024-01-02"},{"cvss_score":5.5,"headline":"Memory corruption in n/a","id":"CVE-2023-49556","kev_date_added":null,"published":"2024-01-02"},{"cvss_score":5.5,"headline":"Denial of service in n/a","id":"CVE-2023-49557","kev_date_added":null,"published":"2024-01-02"}],"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":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-06-03","vendors":["n/a"]},"summary":"A remote attacker can cause a denial of service in the YASM assembler via the expand_mmac_params function.","url":"https://insights.sbomify.com/CVE-2023-49558/"}
