CVE-2023-31608Public exploitNetwork attack vector

Database crash via signed integer overflow

Published May 15, 2023 · Updated Jan 23, 2025

Integer overflow in OpenLink Virtuoso Open-Source Edition 7.2.9 allows remote attackers to crash the database via a crafted SQL query. The artm_div_int path divides the minimum signed 64-bit integer by -1 without rejecting the unrepresentable result, triggering an arithmetic fault. Any remote attacker able to submit SQL can interrupt the database process; no confidentiality or integrity impact is reported.
