CVE-2023-31626Public exploitNetwork attack vector

Service interruption via duplicate MIN aggregates

Published May 15, 2023 · Updated Jan 23, 2025

Denial of service in OpenLink Virtuoso Open-Source Edition 7.2.9 allows attackers to hang a SQL client via a crafted query. A SELECT over an empty table with duplicate MIN aggregates reaches gpf_notice after print_object2; the upstream report does not identify the invalid state passed to that routine. A debug build crashes, while the published Docker build leaves the invoking client stuck without crashing the server, bounding default-build impact to a client or session hang.
