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-2009-2414 in the wild and no public exploit code.\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-2009-2414/ (Markdown: https://insights.sbomify.com/CVE-2009-2414/index.md)","id":"CVE-2009-2414","markdown":"https://insights.sbomify.com/CVE-2009-2414/index.md","name":"CVE-2009-2414","record":{"aliases":["DEBIAN-CVE-2009-2414","GHSA-pxj8-hpwc-88mp"],"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 crash applications using libxml2 by sending XML with deeply nested DTD element declarations, causing stack exhaustion.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"libxml","vendor":"xmlsoft"},{"product":"libxml2","vendor":"xmlsoft"}],"cvss":{"score":4.3,"severity":"medium","source":"nvd","vector":"AV:N/AC:M/Au:N/C:N/I:N/A:P","version":"2.0"},"cwes":[{"id":"CWE-119","name":"Improper Restriction of Operations within the Bounds of a Memory Buffer"}],"description":"Stack consumption vulnerability in libxml2 2.5.10, 2.6.16, 2.6.26, 2.6.27, and 2.6.32, and libxml 1.8.17, allows context-dependent attackers to cause a denial of service (application crash) via a large depth of element declarations in a DTD, related to a function recursion, as demonstrated by the Codenomicon XML fuzzing framework.","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-2009-2414","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"xmlsoft:libxml2","products":["xmlsoft:libxml2"],"type":"denial_of_service","year":"2009"},"n_packages":0,"n_references":36,"next":{"headline":"Integer overflow in n/a","id":"CVE-2009-2415"},"packages":[],"prev":{"headline":"DO NOT USE THIS CANDIDATE NUMBER.","id":"CVE-2009-2413"},"products":["n/a"],"published":"2009-08-11","related":[{"cvss_score":10,"headline":"Integer overflow in n/a","id":"CVE-2008-4226","kev_date_added":null,"published":"2008-11-25"},{"cvss_score":9.3,"headline":"Integer overflow in n/a","id":"CVE-2011-1944","kev_date_added":null,"published":"2011-09-02"},{"cvss_score":7.8,"headline":"Integer overflow in n/a","id":"CVE-2008-4225","kev_date_added":null,"published":"2008-11-25"}],"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":"2024-08-07","vendors":["n/a"]},"summary":"Attackers can crash applications using libxml2 by sending XML with deeply nested DTD element declarations, causing stack exhaustion.","url":"https://insights.sbomify.com/CVE-2009-2414/"}
