An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2008-4409 exists.\n\nAffected product: Xmlsoft Libxml2. 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-2008-4409/ (Markdown: https://insights.sbomify.com/CVE-2008-4409/index.md)","id":"CVE-2008-4409","markdown":"https://insights.sbomify.com/CVE-2008-4409/index.md","name":"CVE-2008-4409","record":{"aliases":["CVE-2008-4422","GHSA-34h5-p5c9-pjw6"],"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":"Attackers can cause denial of service via memory consumption and crashes by providing malicious XML documents to applications using libxml2.","user_interaction":"required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"libxml2","vendor":"xmlsoft"}],"cvss":{"score":5,"severity":"medium","source":"nvd","vector":"AV:N/AC:L/Au:N/C:N/I:N/A:P","version":"2.0"},"cwes":[{"id":"CWE-399","name":null}],"description":"libxml2 2.7.0 and 2.7.1 does not properly handle \"predefined entities definitions\" in entities, which allows context-dependent attackers to cause a denial of service (memory consumption and application crash), as demonstrated by use of xmllint on a certain XML document, a different vulnerability than CVE-2003-1564 and CVE-2008-3281.","ecosystems":[],"exploits":{"exploitdb":1,"first_seen":"2008-10-02","github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[{"date":"2008-10-02","kind":"exploitdb","ref":"32454","stars":null,"title":"libxml2 - Denial of Service"}],"tier":"weaponised"},"has_fix":true,"headline":"Denial of service in n/a","id":"CVE-2008-4409","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"xmlsoft:libxml2","products":["xmlsoft:libxml2"],"type":"denial_of_service","year":"2008"},"n_packages":0,"n_references":18,"next":{"headline":"Denial of service in n/a","id":"CVE-2008-4410"},"packages":[],"prev":{"headline":"Cross-site scripting in n/a","id":"CVE-2008-4408"},"products":["n/a"],"published":"2008-10-03","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"},{"cvss_score":7.5,"headline":"Nokogiri gem, via libxml, is affected by DoS vulnerabilities","id":"CVE-2017-16932","kev_date_added":null,"published":"2017-11-23"}],"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)"},{"class":"attribution","licence":"GPL-2.0-or-later","name":"Exploit-DB"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-07","vendors":["n/a"]},"summary":"Attackers can cause denial of service via memory consumption and crashes by providing malicious XML documents to applications using libxml2.","url":"https://insights.sbomify.com/CVE-2008-4409/"}
