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-2018-20461 in the wild and no public exploit code.\n\nAffected product: Radare Radare2. 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-2018-20461/ (Markdown: https://insights.sbomify.com/CVE-2018-20461/index.md)","id":"CVE-2018-20461","markdown":"https://insights.sbomify.com/CVE-2018-20461/index.md","name":"CVE-2018-20461","record":{"aliases":["GHSA-h8vf-wgwm-vg6h","UBUNTU-CVE-2018-20461"],"analysis":{"component_type":"developer_tool","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"radare2 reverse engineering tool","requires_auth":"none","summary":"Attackers can cause a denial-of-service crash in radare2 by crafting a malicious binary file, affecting users analyzing untrusted binaries.","user_interaction":"required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"radare2","vendor":"radare"}],"cvss":{"score":5.5,"severity":"medium","source":"nvd","vector":"CVSS:3.0/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H","version":"3.0"},"cwes":[{"id":"CWE-125","name":"Out-of-bounds Read"}],"description":"In radare2 prior to 3.1.1, core_anal_bytes in libr/core/cmd_anal.c allows attackers to cause a denial-of-service (application crash caused by out-of-bounds read) by crafting a binary 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":false,"headline":"Denial of service in n/a","id":"CVE-2018-20461","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"radare:radare2","products":["radare:radare2"],"type":"denial_of_service","year":"2018"},"n_packages":0,"n_references":2,"next":{"headline":"Cross-site scripting in n/a","id":"CVE-2018-20462"},"packages":[],"prev":{"headline":"Memory corruption in n/a","id":"CVE-2018-20460"},"products":["n/a"],"published":"2018-12-25","related":[{"cvss_score":10,"headline":"Buffer Overflow and Potential Code Execution in Radare2","id":"CVE-2025-1864","kev_date_added":null,"published":"2025-03-03"},{"cvss_score":10,"headline":"Out-of-bounds Write in radare2","id":"CVE-2025-1744","kev_date_added":null,"published":"2025-02-28"},{"cvss_score":10,"headline":"Denial of service in radare2","id":"CVE-2021-32494","kev_date_added":null,"published":"2023-07-07"},{"cvss_score":10,"headline":"Use after free in radare2","id":"CVE-2021-32495","kev_date_added":null,"published":"2023-07-07"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2024-29646","kev_date_added":null,"published":"2024-12-17"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2023-46569","kev_date_added":null,"published":"2023-10-28"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2023-46570","kev_date_added":null,"published":"2023-10-28"}],"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":"2024-09-16","vendors":["n/a"]},"summary":"Attackers can cause a denial-of-service crash in radare2 by crafting a malicious binary file, affecting users analyzing untrusted binaries.","url":"https://insights.sbomify.com/CVE-2018-20461/"}
