CVE-2023-36367Public exploitNetwork attack vector

Server crash via traced NULL BLOB comparison

Published Jun 22, 2023 · Updated Dec 2, 2024

Denial of service in MonetDB Server 11.45.17 and 11.46.0 allows remote attackers to crash the server with crafted SQL statements. The published reproducer traces a comparison between a nullable BLOB column containing NULL and a string, which reaches BLOBcmp and terminates mserver5. Network reachability to the SQL service is sufficient according to NVD, and the process crash interrupts database service.
