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-2018-7643 in the wild and no public exploit code.\n\nAffected product: Gnu Binutils. 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-2018-7643/ (Markdown: https://insights.sbomify.com/CVE-2018-7643/index.md)","id":"CVE-2018-7643","markdown":"https://insights.sbomify.com/CVE-2018-7643/index.md","name":"CVE-2018-7643","record":{"aliases":["ALPINE-CVE-2018-7643","DEBIAN-CVE-2018-7643","GHSA-v67x-fvwh-9f63","UBUNTU-CVE-2018-7643"],"analysis":{"component_type":"developer_tool","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"GNU Binutils","requires_auth":"none","summary":"Remote attackers can cause denial of service via integer overflow in GNU Binutils when processing crafted ELF files.","user_interaction":"required","vuln_class":"integer_overflow"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"binutils","vendor":"gnu"},{"product":"enterprise_linux_desktop","vendor":"redhat"},{"product":"enterprise_linux_server","vendor":"redhat"},{"product":"enterprise_linux_workstation","vendor":"redhat"}],"cvss":{"score":7.8,"severity":"high","source":"nvd","vector":"CVSS:3.0/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.0"},"cwes":[{"id":"CWE-190","name":"Integer Overflow or Wraparound"}],"description":"The display_debug_ranges function in dwarf.c in GNU Binutils 2.30 allows remote attackers to cause a denial of service (integer overflow and application crash) or possibly have unspecified other impact via a crafted ELF file, as demonstrated by objdump.","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-2018-7643","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"gnu:binutils","products":["gnu:binutils","redhat:enterprise_linux_desktop","redhat:enterprise_linux_server","redhat:enterprise_linux_workstation"],"type":"integer_overflow","year":"2018"},"n_packages":0,"n_references":7,"next":{"headline":"SimpleSAMLphp Improper Verification of Cryptographic Signature","id":"CVE-2018-7644"},"packages":[],"prev":{"headline":"Null dereference in n/a","id":"CVE-2018-7642"},"products":["n/a"],"published":"2018-03-02","related":[{"cvss_score":9.8,"headline":"Null dereference in n/a","id":"CVE-2017-7614","kev_date_added":null,"published":"2017-04-09"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2014-9939","kev_date_added":null,"published":"2017-03-21"},{"cvss_score":9.1,"headline":"Information disclosure in n/a","id":"CVE-2017-7226","kev_date_added":null,"published":"2017-03-22"},{"cvss_score":9.1,"headline":"Information disclosure in n/a","id":"CVE-2017-6969","kev_date_added":null,"published":"2017-03-17"},{"cvss_score":8.8,"headline":"Denial of service in n/a","id":"CVE-2020-19726","kev_date_added":null,"published":"2023-08-22"},{"cvss_score":7.8,"headline":"Binutils: binutils: arbitrary code execution via malformed xcoff object file processing","id":"CVE-2026-6846","kev_date_added":null,"published":"2026-04-22"},{"cvss_score":7.8,"headline":"Memory corruption in n/a","id":"CVE-2022-44840","kev_date_added":null,"published":"2023-08-22"}],"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":"2024-08-05","vendors":["n/a"]},"summary":"Remote attackers can cause denial of service via integer overflow in GNU Binutils when processing crafted ELF files.","url":"https://insights.sbomify.com/CVE-2018-7643/"}
