An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2025-66865 exists.\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-2025-66865/ (Markdown: https://insights.sbomify.com/CVE-2025-66865/index.md)","id":"CVE-2025-66865","markdown":"https://insights.sbomify.com/CVE-2025-66865/index.md","name":"CVE-2025-66865","record":{"aliases":["DEBIAN-CVE-2025-66865","ECHO-f200-77a9-2ba8","GHSA-w539-2pgj-g759","UBUNTU-CVE-2025-66865"],"analysis":{"component_type":"developer_tool","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"BinUtils demangler","requires_auth":"none","summary":"Attackers can cause a denial of service in BinUtils by providing a crafted PE file to the demangler.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"binutils","vendor":"gnu"}],"cvss":{"score":7.5,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-121","name":"Stack-based Buffer Overflow"}],"description":"An issue was discovered in function d_print_comp_inner in file cp-demangle.c in BinUtils 2.26 allows attackers to cause a denial of service via crafted PE file.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":true,"headline":"Denial of service in n/a","id":"CVE-2025-66865","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"gnu:binutils","products":["gnu:binutils"],"type":"denial_of_service","year":"2025"},"n_packages":0,"n_references":1,"next":{"headline":"Denial of service in n/a","id":"CVE-2025-66866"},"packages":[],"prev":{"headline":"Denial of service in n/a","id":"CVE-2025-66864"},"products":["n/a"],"published":"2025-12-29","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":"yes","exploitation":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-12-30","vendors":["n/a"]},"summary":"Attackers can cause a denial of service in BinUtils by providing a crafted PE file to the demangler.","url":"https://insights.sbomify.com/CVE-2025-66865/"}
