Detailed Information:
This event is generated when an attempt is made to exploit a known vulnerability in an Oracle database implementation. Multiple buffer overflow conditions are present in numerous packages and procedures.

Exploitation of these vulnerable procedures may allow an attacker to execute code of their choosing as the user running the database. In the case of databases running on Microsoft Windows platforms, this is the Local System account which may mean a compromise of the operating system as well as the database.

This event indicates that an attempt has been made to exploit a vulnerability in the procedure sys.pbsde.init.
