CVE-2023-40687

Name of the Vulnerable Software and Affected Versions IBM DB2 for Linux, UNIX and Windows (includes Db2 Connect Server) versions 10.5, 11.1, and 11.5

Description The issue exists due to insufficient input validation in the system, allowing a remote attacker to cause a denial of service using a specially crafted RUNSTATS command on an 8TB table.

Recommendations For versions 10.5, 11.1, and 11.5, consider restricting access to the RUNSTATS command on large tables as a temporary workaround until a patch is available. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
