Oracle Database Server is "a family of database products that range from personal databases to enterprise solutions". Remote exploitation of a buffer overflow vulnerability in the DBMS_AQELM package in Oracle Corp.'s Oracle Database product allows attackers to execute arbitrary code with the privileges of the database user.
Vulnerable Systems:
* Oracle Database version 10.2.0.3 and 11.1.0.6 with the October 2007 CPU applied
This vulnerability exists due to improper input validation when handling a parameter passed to a procedure within the DBMS_AQELM package. Since the parameter is not properly validated, providing a long string can cause a buffer overflow to occur. This results in corruption of the database and could allow for the execution of arbitrary code as the database user.
Analysis:
Exploitation of this vulnerability results in database corruption and possibly arbitrary code execution with the privileges of the oracle user on Unix, and the "SYSTEM" user on Windows. This grants an attacker full reign over the database.
In order to exploit this vulnerability, an attacker must have access to a database account with privilege to execute the DBMS_AQELM package. In a default install, users with the Advanced Queue Administrator Role (AQ_ADMINISTRATOR_ROLE) have this privilege.
