Overview
IBM Db2 for Linux, UNIX and Windows (includes Db2 Connect Server) version 11.5 contains a vulnerability that allows an authenticated user with CONNECT privileges to cause a denial of service using a specially crafted query. The vulnerability was discovered and assigned CVE-2023-47141, with IBM X-Force ID 270264.
