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-2020-16593 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-2020-16593/ (Markdown: https://insights.sbomify.com/CVE-2020-16593/index.md)","id":"CVE-2020-16593","markdown":"https://insights.sbomify.com/CVE-2020-16593/index.md","name":"CVE-2020-16593","record":{"aliases":["DEBIAN-CVE-2020-16593","GHSA-vpwc-qjh8-q22p"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"GNU Binutils BFD library","requires_auth":"none","summary":"A crafted file can trigger a null pointer dereference in the BFD library, causing a denial of service in tools like addr2line.","user_interaction":"required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"binutils","vendor":"gnu"},{"product":"cloud_backup","vendor":"netapp"},{"product":"ontap_select_deploy_administration_utility","vendor":"netapp"},{"product":"solidfire_\\\u0026_hci_management_node","vendor":"netapp"}],"cvss":{"score":5.5,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-476","name":"NULL Pointer Dereference"}],"description":"A Null Pointer Dereference vulnerability exists in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.35, in scan_unit_for_symbols, as demonstrated in addr2line, that can cause a denial of service via a crafted file.","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":"Null dereference in n/a","id":"CVE-2020-16593","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"gnu:binutils","products":["gnu:binutils","netapp:cloud_backup","netapp:ontap_select_deploy_administration_utility","netapp:solidfire_\\\u0026_hci_management_node"],"type":"null_dereference","year":"2020"},"n_packages":0,"n_references":3,"next":{"headline":"DO NOT USE THIS CANDIDATE NUMBER.","id":"CVE-2020-16598"},"packages":[],"prev":{"headline":"Use after free in n/a","id":"CVE-2020-16592"},"products":["n/a"],"published":"2020-12-09","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":"2024-08-04","vendors":["n/a"]},"summary":"A crafted file can trigger a null pointer dereference in the BFD library, causing a denial of service in tools like addr2line.","url":"https://insights.sbomify.com/CVE-2020-16593/"}
