Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2007-0556 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-2007-0556/ (Markdown: https://insights.sbomify.com/CVE-2007-0556/index.md)","id":"CVE-2007-0556","markdown":"https://insights.sbomify.com/CVE-2007-0556/index.md","name":"CVE-2007-0556","record":{"aliases":["GHSA-c63f-g8cg-38ww"],"analysis":{"component_type":"database","fix_type":"upgrade","impacts":["denial_of_service","data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"PostgreSQL database","requires_auth":"low_privilege","summary":"Authenticated users can crash the server or read arbitrary memory via a crafted SQL statement due to improper query plan validation.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"postgresql","vendor":"postgresql"}],"cvss":{"score":6.6,"severity":"medium","source":"nvd","vector":"AV:N/AC:H/Au:S/C:C/I:N/A:C","version":"2.0"},"cwes":[],"description":"The query planner in PostgreSQL before 8.0.11, 8.1 before 8.1.7, and 8.2 before 8.2.2 does not verify that a table is compatible with a \"previously made query plan,\" which allows remote authenticated users to cause a denial of service (server crash) and possibly access database content via an \"ALTER COLUMN TYPE\" SQL statement, which can be leveraged to read arbitrary memory from the server.","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":"Memory corruption in n/a","id":"CVE-2007-0556","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"postgresql:postgresql","products":["postgresql:postgresql"],"type":"memory_corruption","year":"2007"},"n_packages":0,"n_references":34,"next":{"headline":"Privilege escalation in n/a","id":"CVE-2007-0557"},"packages":[],"prev":{"headline":"Denial of service in n/a","id":"CVE-2007-0555"},"products":["n/a"],"published":"2007-02-06","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":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-07","vendors":["n/a"]},"summary":"Authenticated users can crash the server or read arbitrary memory via a crafted SQL statement due to improper query plan validation.","url":"https://insights.sbomify.com/CVE-2007-0556/"}
