Summary:
This event is generated when an attempt is made to exploit a known vulnerability in a Oracle database implementation.

--
Impact:
Serious. Execution of arbitrary code may be possible. A Denial of Service (DoS) condition may also be caused.

--
Detailed Information:
An attacker can attempt to connect to a database using an overly long user name value. This can cause a buffer overflow, allowing an attacker to execute arbitrary code.

If you are running Oracle on a Windows server, make sure that the variable $ORACLE_PORTS is set to a value of "any".

--
Affected Systems:
Oracle8, Oracle8i, and Oracle9i

--
Attack Scenarios:
An attacker can attempt to connect to a database supplying the user an overly long value.  The result could permit the attacker to gain escalated privileges and run code of their choosing.

--
Ease of Attack:
Simple.

--
False Positives:
None known.

--
False Negatives:
None known.

--
Corrective Action:
Ensure the system is using an up to date version of the software and has had all vendor supplied patches applied.
