Unspecified vulnerability in IBM Tivoli Monitoring Agent (ITMA), as used in IBM DB2 9.5 before FP9 on UNIX, allows local users to gain privileges via unknown vectors.

The XML feature in IBM DB2 9.5 before FP9, 9.7 through FP5, and 9.8 through FP4 allows remote authenticated users to cause a denial of service (infinite loop) by calling the XMLPARSE function with a crafted string expression.

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.

IBM DB2 9.5 before FP9, 9.7 through FP5, and 9.8 through FP4 does not properly check variables, which allows remote authenticated users to bypass intended restrictions on viewing table data by leveraging the CREATEIN privilege to execute crafted SQL CREATE VARIABLE statements.

IBM DB2 9.5 before FP7 and 9.7 before FP4 on Linux, UNIX, and Windows does not properly enforce privilege requirements for table access, which allows remote authenticated users to modify SYSSTAT.TABLES statistics columns via an UPDATE statement. NOTE: some of these details are obtained from third party information.

IBM DB2 9.5 before FP7 and 9.7 before FP4 on Linux, UNIX, and Windows does not properly revoke role membership from groups, which allows remote authenticated users to execute non-DDL statements by leveraging previous inherited possession of a role, a different vulnerability than CVE-2011-0757. NOTE: some of these details are obtained from third party information.

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.

The Net Search Extender (NSE) implementation in the Text Search component in IBM DB2 UDB 9.5 before FP6a does not properly handle an alphanumeric Fuzzy search, which allows remote authenticated users to cause a denial of service (memory consumption and system hang) via the db2ext.textSearch function.

The Security component in IBM DB2 UDB 9.5 before FP6a logs AUDIT events by using a USERID and an AUTHID value corresponding to the instance owner, instead of a USERID and an AUTHID value corresponding to the logged-in user account, which makes it easier for remote authenticated users to execute Audit administration commands without discovery.

Memory leak in the Relational Data Services component in IBM DB2 UDB 9.5 before FP6a allows remote authenticated users to cause a denial of service (heap memory consumption) by executing a (1) user-defined function (UDF) or (2) stored procedure while using a different code page than the database server.

Memory leak in the Relational Data Services component in IBM DB2 UDB 9.5 before FP6a, when the connection concentrator is enabled, allows remote authenticated users to cause a denial of service (heap memory consumption) by using a different code page than the database server.

The "Query Compiler, Rewrite, Optimizer" component in IBM DB2 UDB 9.5 before FP6a allows remote authenticated users to cause a denial of service (CPU consumption) via a crafted query involving certain UNION ALL views, leading to an indefinitely large amount of compilation time.

The Install component in IBM DB2 UDB 9.5 before FP6a on Linux, UNIX, and Windows enforces an unintended limit on password length, which makes it easier for attackers to obtain access via a brute-force attack.

The Engine Utilities component in IBM DB2 UDB 9.5 before FP6a uses world-writable permissions for the sqllib/cfg/db2sprf file, which might allow local users to gain privileges by modifying this file.

The DRDA Services component in IBM DB2 UDB 9.5 before FP6a allows remote authenticated users to cause a denial of service (database server ABEND) by using the client CLI on Linux, UNIX, or Windows for executing a prepared statement with a large number of parameter markers.

Stack-based buffer overflow in the validateUser implementation in the com.ibm.db2.das.core.DasSysCmd function in db2dasrrm in the DB2 Administration Server (DAS) component in IBM DB2 9.1 before FP10, 9.5 before FP6a, and 9.7 before FP3 allows remote attackers to execute arbitrary code via a long username string.

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."

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.
