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, i.e. 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 vulnerability in the Oracle Database products. The flaw can be triggered by a crafted call to a certain function. An authenticated attacker may trigger the vulnerability to result in code injection and execution on the target host within the security context of the Database service, normally System. In 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 services will be unavailable until the process is restarted manually. In case of a more sophisticated attack where code injection is successful, the behavior 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, normally System.
