CVE-2023-29267Network attack vector

Authenticated server crash via crafted SQL statement

Published Jun 12, 2024 · Updated Aug 28, 2024

Denial of service in IBM Db2 10.5, 11.1, and 11.5 allows remote authenticated users to crash the server via crafted SQL. Db2 processing of a crafted SELECT against certain table types triggers an internal trap; IBM withholds the affected functionality and replication details. Exploitation requires database access and a specific configuration, and the documented consequence is a server crash without data disclosure or modification.
