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-2017-16932 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- nokogiri (RubyGems): affected all versions; fixed in 1.8.1\n- nokogiri (RubyGems): affected all versions; fixed in 1.8.1\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-2017-16932/ (Markdown: https://insights.sbomify.com/CVE-2017-16932/index.md)","id":"CVE-2017-16932","markdown":"https://insights.sbomify.com/CVE-2017-16932/index.md","name":"CVE-2017-16932","record":{"aliases":["ALPINE-CVE-2017-16932","CLEANSTART-2026-ZZ43930","DEBIAN-CVE-2017-16932","ECHO-4ae1-cce4-b9d4","GHSA-x2fm-93ww-ggvx","UBUNTU-CVE-2017-16932","USN-3504-1"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"XML parsing library","requires_auth":"none","summary":"An attacker can cause a denial of service via infinite recursion in libxml2 parameter entity parsing, affecting applications using this library.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"libxml2","vendor":"xmlsoft"}],"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-835","name":"Loop with Unreachable Exit Condition"}],"description":"parser.c in libxml2 before 2.9.5 does not prevent infinite recursion in parameter entities.","ecosystems":["RubyGems"],"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":"Nokogiri gem, via libxml, is affected by DoS vulnerabilities","id":"CVE-2017-16932","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"RubyGems","product":"xmlsoft:libxml2","products":["xmlsoft:libxml2"],"type":"denial_of_service","year":"2017"},"n_packages":2,"n_references":10,"next":{"headline":"Privilege escalation in n/a","id":"CVE-2017-16933"},"packages":[{"ecosystem":"RubyGems","fixed":["1.8.1"],"introduced":["0"],"last_affected":[],"package":"nokogiri","purl":null,"source":"GHSA-x2fm-93ww-ggvx"},{"ecosystem":"RubyGems","fixed":["1.8.1"],"introduced":["0"],"last_affected":[],"package":"nokogiri","purl":"pkg:gem/nokogiri","source":"GHSA-x2fm-93ww-ggvx"}],"prev":{"headline":"XML external entity in n/a","id":"CVE-2017-16931"},"products":["n/a"],"published":"2017-11-23","related":[{"cvss_score":9.8,"headline":"XML external entity in n/a","id":"CVE-2017-16931","kev_date_added":null,"published":"2017-11-23"},{"cvss_score":9.1,"headline":"Information disclosure in n/a","id":"CVE-2017-8872","kev_date_added":null,"published":"2017-05-10"},{"cvss_score":8.1,"headline":"Use after free in libxml2","id":"CVE-2022-49043","kev_date_added":null,"published":"2025-01-26"},{"cvss_score":8,"headline":"Memory corruption in libxml2","id":"CVE-2026-86140","kev_date_added":null,"published":"2026-09-05"},{"cvss_score":7.5,"headline":"Memory corruption in n/a","id":"CVE-2024-34459","kev_date_added":null,"published":"2024-05-13"},{"cvss_score":7.5,"headline":"Use after free in n/a","id":"CVE-2024-25062","kev_date_added":null,"published":"2024-02-04"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"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":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-10-14","vendors":["n/a"]},"summary":"An attacker can cause a denial of service via infinite recursion in libxml2 parameter entity parsing, affecting applications using this library.","url":"https://insights.sbomify.com/CVE-2017-16932/"}
