Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2007-4769 in the wild and no public exploit code.\n\nAffected product: Postgresql Postgresql. 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-2007-4769/ (Markdown: https://insights.sbomify.com/CVE-2007-4769/index.md)","id":"CVE-2007-4769","markdown":"https://insights.sbomify.com/CVE-2007-4769/index.md","name":"CVE-2007-4769","record":{"aliases":["GHSA-66vv-jcch-hx6x"],"analysis":{"component_type":"database","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"PostgreSQL database","requires_auth":"low_privilege","summary":"Remote authenticated users can crash the PostgreSQL backend via a crafted regular expression in the TCL parser, causing denial of service.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"postgresql","vendor":"postgresql"},{"product":"tcl_tk","vendor":"tcl_tk"}],"cvss":{"score":6.8,"severity":"medium","source":"nvd","vector":"AV:N/AC:L/Au:S/C:N/I:N/A:C","version":"2.0"},"cwes":[{"id":"CWE-189","name":null}],"description":"The regular expression parser in TCL before 8.4.17, as used in PostgreSQL 8.2 before 8.2.6, 8.1 before 8.1.11, 8.0 before 8.0.15, and 7.4 before 7.4.19, allows remote authenticated users to cause a denial of service (backend crash) via an out-of-bounds backref number.","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-2007-4769","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"postgresql:postgresql","products":["postgresql:postgresql"],"type":"denial_of_service","year":"2007"},"n_packages":0,"n_references":39,"next":{"headline":"Memory corruption in n/a","id":"CVE-2007-4770"},"packages":[],"prev":{"headline":"Memory corruption in n/a","id":"CVE-2007-4768"},"products":["n/a"],"published":"2008-01-09","related":[{"cvss_score":10,"headline":"Information disclosure in n/a","id":"CVE-2013-1902","kev_date_added":null,"published":"2013-04-04"},{"cvss_score":10,"headline":"Information disclosure in n/a","id":"CVE-2013-1903","kev_date_added":null,"published":"2013-04-04"},{"cvss_score":10,"headline":"Privilege escalation in n/a","id":"CVE-2007-3279","kev_date_added":null,"published":"2007-06-19"},{"cvss_score":10,"headline":"Integer overflow in n/a","id":"CVE-2002-1399","kev_date_added":null,"published":"2003-01-08"},{"cvss_score":9.1,"headline":"Information disclosure in n/a","id":"CVE-2016-3065","kev_date_added":null,"published":"2016-04-11"},{"cvss_score":9,"headline":"Code injection in n/a","id":"CVE-2007-3280","kev_date_added":null,"published":"2007-06-19"},{"cvss_score":8.8,"headline":"PostgreSQL tsvector and tsquery undersize allocations, via integer wraparound","id":"CVE-2026-14662","kev_date_added":null,"published":"2026-08-13"}],"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":"Remote authenticated users can crash the PostgreSQL backend via a crafted regular expression in the TCL parser, causing denial of service.","url":"https://insights.sbomify.com/CVE-2007-4769/"}
