Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2009-4439 in the wild and no public exploit code.\n\nAffected product: Ibm Db2. 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-2009-4439/ (Markdown: https://insights.sbomify.com/CVE-2009-4439/index.md)","id":"CVE-2009-4439","markdown":"https://insights.sbomify.com/CVE-2009-4439/index.md","name":"CVE-2009-4439","record":{"aliases":["GHSA-wwmg-hpgx-829f"],"analysis":{"component_type":"database","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"IBM DB2 database","requires_auth":"low_privilege","summary":"Remote authenticated users can crash the IBM DB2 database instance by compiling a specific SQL query, causing a denial of service.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"db2","vendor":"ibm"}],"cvss":{"score":4,"severity":"medium","source":"nvd","vector":"AV:N/AC:L/Au:S/C:N/I:N/A:P","version":"2.0"},"cwes":[],"description":"Unspecified vulnerability in the Query Compiler, Rewrite, and Optimizer component in IBM DB2 9.5 before FP5 allows remote authenticated users to cause a denial of service (instance crash) by compiling a SQL query.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Denial of service in n/a","id":"CVE-2009-4439","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"ibm:db2","products":["ibm:db2"],"type":"denial_of_service","year":"2009"},"n_packages":0,"n_references":7,"next":{"headline":"Race condition in n/a","id":"CVE-2009-4440"},"packages":[],"prev":{"headline":"Missing authorization in n/a","id":"CVE-2009-4438"},"products":["n/a"],"published":"2009-12-28","related":[{"cvss_score":10,"headline":"IBM DB2 9.5 uses world-writable permissions for nodes.reg, which has unspecified impact and attack vectors.","id":"CVE-2012-1797","kev_date_added":null,"published":"2012-03-20"},{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2010-3731","kev_date_added":null,"published":"2010-10-05"},{"cvss_score":10,"headline":"Other in n/a","id":"CVE-2010-3193","kev_date_added":null,"published":"2010-08-31"},{"cvss_score":10,"headline":"Other in n/a","id":"CVE-2009-4335","kev_date_added":null,"published":"2009-12-16"},{"cvss_score":10,"headline":"Missing authorization in n/a","id":"CVE-2009-3473","kev_date_added":null,"published":"2009-09-29"},{"cvss_score":10,"headline":"Privilege escalation in n/a","id":"CVE-2008-6820","kev_date_added":null,"published":"2009-06-03"},{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2008-6821","kev_date_added":null,"published":"2009-06-03"}],"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":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-09-16","vendors":["n/a"]},"summary":"Remote authenticated users can crash the IBM DB2 database instance by compiling a specific SQL query, causing a denial of service.","url":"https://insights.sbomify.com/CVE-2009-4439/"}
