Who is Vulnerable?
Vulnerability Description	Oracle Database Server is an enterprise-level relational database application suite. To extend the functionality of the Oracle Database Server, extra packages of related program objects, e.g., procedures, functions, variables, constants, cursors, and exceptions, are provided in order to better manage the data. The included stored procedures and functions, or subprograms, are called by name and optionally passed a set of parameters. They are essentially a set of SQL statements that are stored on the server-side, usually as precompiled SQL. There exists a buffer overflow in Oracle Database Server. The vulnerability is due improper input validation of parameters sent to a procedure in the DBMS_AQELM package. A remote authenticated attacker can exploit this vulnerability by sending a specially crafted SQL statement to the target server, potentially causing database corruption or arbitrary code injection and execution with the privileges of the affected process. In a case of an attack where code injection is not successful, the affected service may terminate upon processing of the malicious SQL statement. If the service is not configured to restart automatically, the service will be unavailable until the process is restarted manually. However, it has been noticed that Oracle data files can get corrupted in a way that even manual restart will not resume the service. In that case, only a backup image can be used to recover the database service. In a case of a more sophisticated attack, where code injection is successful, the behaviour of the target host is entirely dependent on the intended function of the injected code. The code in such a case would execute within the security context of the service process. On Windows systems, the affected service is running with System privileges, in default configuration.
