{"id":"JLSEC-2026-601","details":"Integer wraparound in multiple PostgreSQL server features allows an unprivileged database user to cause the server to undersize an allocation and write out-of-bounds.  This may execute arbitrary code as the operating system user running the database.  In applications that pass gigabyte-scale user inputs to the relevant database functions, the application input provider may achieve a segmentation fault.  Versions before PostgreSQL 18.4, 17.10, 16.14, 15.18, and 14.23 are affected.","modified":"2026-06-08T14:00:04.167201767Z","published":"2026-06-08T13:54:13.679Z","upstream":["CVE-2026-6473"],"database_specific":{"license":"CC-BY-4.0","sources":[{"html_url":"https://nvd.nist.gov/vuln/detail/CVE-2026-6473","modified":"2026-05-18T14:59:59.747Z","imported":"2026-06-08T13:34:09.445Z","published":"2026-05-14T14:16:24.883Z","url":"https://services.nvd.nist.gov/rest/json/cves/2.0?cveId=CVE-2026-6473","id":"CVE-2026-6473","database_specific":{"status":"Analyzed"}}]},"references":[{"type":"WEB","url":"https://www.postgresql.org/support/security/CVE-2026-6473/"}],"affected":[{"package":{"name":"LibPQ_jll","ecosystem":"Julia","purl":"pkg:julia/LibPQ_jll?uuid=08be9ffa-1c94-5ee5-a977-46a84ec9b350"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"16.14.0+0"}]}],"database_specific":{"source":"https://github.com/JuliaLang/SecurityAdvisories.jl/tree/generated/osv/2026/JLSEC-2026-601.json"}}],"schema_version":"1.7.5"}
