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-2025-66862 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-2025-66862/ (Markdown: https://insights.sbomify.com/CVE-2025-66862/index.md)","id":"CVE-2025-66862","markdown":"https://insights.sbomify.com/CVE-2025-66862/index.md","name":"CVE-2025-66862","record":{"aliases":["DEBIAN-CVE-2025-66862","ECHO-d4cb-fb13-fce0","GHSA-rhg5-g54m-7cq3","UBUNTU-CVE-2025-66862"],"analysis":{"component_type":"developer_tool","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"BinUtils","requires_auth":"none","summary":"Attackers can cause a denial of service in BinUtils by providing a crafted PE file that triggers a buffer overflow.","user_interaction":"not_required","vuln_class":"memory_corruption"},"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-122","name":"Heap-based Buffer Overflow"}],"description":"A buffer overflow vulnerability in function gnu_special in file cplus-dem.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":"Memory corruption in n/a","id":"CVE-2025-66862","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"gnu:binutils","products":["gnu:binutils"],"type":"memory_corruption","year":"2025"},"n_packages":0,"n_references":1,"next":{"headline":"Denial of service in n/a","id":"CVE-2025-66863"},"packages":[],"prev":{"headline":"Denial of service in n/a","id":"CVE-2025-66861"},"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 that triggers a buffer overflow.","url":"https://insights.sbomify.com/CVE-2025-66862/"}
