db2pd in the Problem Determination component in IBM DB2 9.1 before FP7 and 9.5 before FP5 allows attackers to cause a denial of service (NULL pointer dereference and application termination) via unspecified vectors.
The Client Interfaces component in IBM DB2 8.2 before FP18, 9.1 before FP8, 9.5 before FP5, and 9.7 before FP1 does not validate an unspecified pointer, which allows attackers to overwrite "external memory" via unknown vectors, related to a missing "check for null pointers."
The Query Compiler, Rewrite, and Optimizer component in IBM DB2 9.1 before FP8, 9.5 before FP5, and 9.7 before FP1 does not enforce privilege requirements for access to a (1) sequence or (2) global-variable object, which allows remote authenticated users to make use of data via unspecified vectors.
dasauto in IBM DB2 8 before FP18, 9.1 before FP8, 9.5 before FP4, and 9.7 before FP1 permits execution by unprivileged user accounts, which has unspecified impact and local attack vectors.
The Self Tuning Memory Manager (STMM) component in IBM DB2 9.1 before FP8, 9.5 before FP5, and 9.7 before FP1 uses 0666 permissions for the STMM log file, which allows local users to cause a denial of service or have unspecified other impact by writing to this file.
IBM DB2 9.1 before FP8 does not require the SETSESSIONUSER privilege for the SET SESSION AUTHORIZATION statement, which has unspecified impact and remote attack vectors.
IBM DB2 8 before FP18, 9.1 before FP8, and 9.5 before FP4 allows remote authenticated users to bypass intended access restrictions, and update, insert, or delete table rows, via unspecified vectors.
IBM DB2 8 before FP18, 9.1 before FP8, 9.5 before FP4, and 9.7 before FP2 does not perform the expected drops of certain table functions upon a loss of privileges by the functions' definers, which has unspecified impact and remote attack vectors.
Unspecified vulnerability in IBM DB2 9.1 before FP9, 9.5 before FP6, and 9.7 before FP2 on Windows Server 2008 allows attackers to cause a denial of service (trap) via vectors involving "special group and user enumeration."
Unspecified vulnerability in the DB2STST program in IBM DB2 9.1 before FP9, 9.5 before FP6, and 9.7 before FP2 has unknown impact and attack vectors.
The DB2DART program in IBM DB2 9.1 before FP9, 9.5 before FP6, and 9.7 before FP2 allows attackers to bypass intended file access restrictions via unspecified vectors related to overwriting files owned by an instance owner.
IBM DB2 9.1 before FP10, 9.5 before FP6a, and 9.7 before FP2 on Linux, UNIX, and Windows does not properly revoke the DBADM authority, which allows remote authenticated users to execute non-DDL statements by leveraging previous possession of this authority.
Buffer overflow in the DB2 Administration Server (DAS) component in IBM DB2 9.1 before FP10, 9.5 before FP7, and 9.7 before FP3 on Linux, UNIX, and Windows allows remote attackers to execute arbitrary code via unspecified vectors.
Integer signedness error in the db2dasrrm process in the DB2 Administration Server (DAS) in IBM DB2 9.1 through FP11, 9.5 before FP9, and 9.7 through FP5 on UNIX platforms allows remote attackers to execute arbitrary code via a crafted request that triggers a heap-based buffer overflow.
IBM DB2 9.1 before FP11, 9.5 before FP9, 9.7 before FP5, and 9.8 before FP4 allows remote attackers to cause a denial of service (daemon crash) via a crafted Distributed Relational Database Architecture (DRDA) request.
