Heap-based buffer overflow in IBM DB2 9.1 before FP9, 9.5 before FP6, and 9.7 before FP2 allows remote authenticated users to have an unspecified impact via a SELECT statement that has a long column name generated with the REPEAT function.
Unspecified vulnerability in the Query Compiler, Rewrite, and Optimizer component in IBM DB2 9.5 before FP5 allows remote authenticated users to cause a denial of service (instance crash) by compiling a SQL query.
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.
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 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.
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.
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 9.5 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.
