IBM Db2 for Linux, UNIX and Windows (includes DB2 Connect Server) 11.5 under certain circumstances could allow an authenticated user to the database to cause a denial of service when a statement is run on columnar tables. IBM X-Force ID: 273393.

IBM Db2 for Linux, UNIX and Windows (includes Db2 Connect Server) 11.5 federated server is vulnerable to a denial of service when a specially crafted cursor is used. IBM X-Force ID: 268759.

IBM DB2 for Linux, UNIX and Windows (includes Db2 Connect Server) 10.5, 11.1, and 11.5 is vulnerable to denial of service with a specially crafted RUNSTATS command on an 8TB table. IBM X-Force ID: 264809.

IBM DB2 9.7 through FP11, 9.8, 10.1 through FP5, and 10.5 through FP7 on Linux, UNIX, and Windows allows remote authenticated users to cause a denial of service (daemon crash) via a crafted DRDA message.

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.

Stack-based buffer overflow in IBM DB2 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 execute arbitrary code via a crafted ALTER MODULE statement.

The OLAP query engine in IBM DB2 and DB2 Connect 9.7 through FP9, 9.8 through FP5, 10.1 through FP3, and 10.5 through FP2, and the DB2 pureScale Feature 9.8 for Enterprise Server Edition, allows remote authenticated users to cause a denial of service (database outage and deactivation) via unspecified vectors.

Directory traversal vulnerability in the UTL_FILE module in IBM DB2 and DB2 Connect 10.1 before FP1 on Windows allows remote authenticated users to modify, delete, or read arbitrary files via a pathname in the file field.

Stack-based buffer overflow in the Java Stored Procedure infrastructure in IBM DB2 9.1 before FP12, 9.5 through FP9, 9.7 through FP6, 9.8 through FP5, and 10.1 allows remote authenticated users to execute arbitrary code by leveraging certain CONNECT and EXECUTE privileges.

IBM DB2 9.1 before FP12, 9.5 through FP9, 9.7 through FP6, 9.8 through FP5, and 10.1 allows remote attackers to read arbitrary XML files via the (1) GET_WRAP_CFG_C or (2) GET_WRAP_CFG_C2 stored procedure.

Directory traversal vulnerability in the SQLJ.DB2_INSTALL_JAR stored procedure in IBM DB2 9.1 before FP12, 9.5 through FP9, 9.7 through FP6, 9.8 through FP5, and 10.1 allows remote attackers to replace JAR files via unspecified vectors.

The chaining functionality in the Distributed Relational Database Architecture (DRDA) module in IBM DB2 9.7 before FP6 and 9.8 before FP5 allows remote attackers to cause a denial of service (NULL pointer dereference, and resource consumption or daemon crash) via a crafted request.
