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-2016-4491 in the wild and no public exploit code.\n\nAffected product: n/a. 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-2016-4491/ (Markdown: https://insights.sbomify.com/CVE-2016-4491/index.md)","id":"CVE-2016-4491","markdown":"https://insights.sbomify.com/CVE-2016-4491/index.md","name":"CVE-2016-4491","record":{"aliases":["DEBIAN-CVE-2016-4491","GHSA-7r8p-jc9c-3r5f","UBUNTU-CVE-2016-4491"],"analysis":{"component_type":"library","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"libiberty demangler","requires_auth":"none","summary":"Remote attackers can cause a denial of service via crafted binaries triggering infinite recursion and buffer overflow in the libiberty demangler.","user_interaction":"required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"libiberty","vendor":"gnu"}],"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-119","name":"Improper Restriction of Operations within the Bounds of a Memory Buffer"}],"description":"The d_print_comp function in cp-demangle.c in libiberty allows remote attackers to cause a denial of service (segmentation fault and crash) via a crafted binary, which triggers infinite recursion and a buffer overflow, related to a node having \"itself as ancestor more than once.\"","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":"Denial of service in n/a","id":"CVE-2016-4491","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2016"},"n_packages":0,"n_references":4,"next":{"headline":"Memory corruption in n/a","id":"CVE-2016-4492"},"packages":[],"prev":{"headline":"Integer overflow in n/a","id":"CVE-2016-4490"},"products":["n/a"],"published":"2017-02-24","related":[{"cvss_score":7.8,"headline":"Integer overflow in n/a","id":"CVE-2016-2226","kev_date_added":null,"published":"2017-02-24"},{"cvss_score":7.5,"headline":"Denial of service in n/a","id":"CVE-2016-6131","kev_date_added":null,"published":"2017-02-07"},{"cvss_score":5.5,"headline":"Use after free in n/a","id":"CVE-2016-4487","kev_date_added":null,"published":"2017-02-24"},{"cvss_score":5.5,"headline":"Use after free in n/a","id":"CVE-2016-4488","kev_date_added":null,"published":"2017-02-24"},{"cvss_score":5.5,"headline":"Integer overflow in n/a","id":"CVE-2016-4489","kev_date_added":null,"published":"2017-02-24"},{"cvss_score":5.5,"headline":"Integer overflow in n/a","id":"CVE-2016-4490","kev_date_added":null,"published":"2017-02-24"}],"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":"2024-08-06","vendors":["n/a"]},"summary":"Remote attackers can cause a denial of service via crafted binaries triggering infinite recursion and buffer overflow in the libiberty demangler.","url":"https://insights.sbomify.com/CVE-2016-4491/"}
