An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2017-12132 in the wild and no public exploit code.\n\nAffected product: Gnu Glibc. 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-2017-12132/ (Markdown: https://insights.sbomify.com/CVE-2017-12132/index.md)","id":"CVE-2017-12132","markdown":"https://insights.sbomify.com/CVE-2017-12132/index.md","name":"CVE-2017-12132","record":{"aliases":["DEBIAN-CVE-2017-12132","GHSA-wjh5-4fq2-439w","UBUNTU-CVE-2017-12132"],"analysis":{"component_type":"operating_system","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":true,"product_category":"GNU C Library","requires_auth":"none","summary":"The glibc DNS stub resolver simplifies off-path DNS spoofing attacks when EDNS is enabled, allowing attackers to bypass DNS security mechanisms.","user_interaction":"not_required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"glibc","vendor":"gnu"}],"cvss":{"score":5.9,"severity":"medium","source":"nvd","vector":"CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:H/A:N","version":"3.0"},"cwes":[{"id":"CWE-770","name":"Allocation of Resources Without Limits or Throttling"}],"description":"The DNS stub resolver in the GNU C Library (aka glibc or libc6) before version 2.26, when EDNS support is enabled, will solicit large UDP responses from name servers, potentially simplifying off-path DNS spoofing attacks due to IP fragmentation.","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":"Other in n/a","id":"CVE-2017-12132","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"gnu:glibc","products":["gnu:glibc"],"type":"other","year":"2017"},"n_packages":0,"n_references":4,"next":{"headline":"Use after free in n/a","id":"CVE-2017-12133"},"packages":[],"prev":{"headline":"Cross-site scripting in n/a","id":"CVE-2017-12131"},"products":["n/a"],"published":"2017-08-01","related":[{"cvss_score":9.8,"headline":"scanf %mc off-by-one heap buffer overflow","id":"CVE-2026-5450","kev_date_added":null,"published":"2026-04-20"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2023-25139","kev_date_added":null,"published":"2023-02-03"},{"cvss_score":9.8,"headline":"Other in n/a","id":"CVE-1999-0199","kev_date_added":null,"published":"2020-10-06"},{"cvss_score":9.8,"headline":"Security feature bypass in glibc","id":"CVE-2019-1010022","kev_date_added":null,"published":"2019-07-15"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2005-3590","kev_date_added":null,"published":"2019-04-10"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2017-18269","kev_date_added":null,"published":"2018-05-18"},{"cvss_score":9.8,"headline":"Integer overflow in n/a","id":"CVE-2018-11236","kev_date_added":null,"published":"2018-05-18"}],"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":"2024-08-05","vendors":["n/a"]},"summary":"The glibc DNS stub resolver simplifies off-path DNS spoofing attacks when EDNS is enabled, allowing attackers to bypass DNS security mechanisms.","url":"https://insights.sbomify.com/CVE-2017-12132/"}
