The SQL engine in IBM DB2 9.5 through FP10, 9.7 through FP9a, 9.8 through FP5, 10.1 through FP4, and 10.5 before FP4 on Linux, UNIX, and Windows allows remote authenticated users to cause a denial of service (daemon crash) via a crafted UNION clause in a subquery of a SELECT statement.

IBM DB2 10.5 before FP4 on Linux and AIX creates temporary files during CDE table LOAD operations, which allows local users to obtain sensitive information by reading a file while a LOAD is occurring.
