Rule:--Sid:2614--Summary:This event is generated when an attempt is made to exploit a knownvulnerability in a Oracle database implementation.--Impact:Serious. Execution of arbitrary code may be possible. A Denial ofService (DoS) condition may also be caused.--Detailed Information:Oracle databases allow a user to set a time zone for the session.The "alter session set time_zone" command contains a programmingerror that may allow an attacker to execute a buffer overflow attack.This overflow is triggered by a long string in the parameter for thecommand.If you are running Oracle on a Windows server, make sure that thevariable $ORACLE_PORTS is set to a value of "any".--Affected Systems:        Oracle 9i--Attack Scenarios:An attacker can supply a long string as the value for this command.The result could permit the attacker to gain escalated privileges andrun code of their choosing. This attack requires an attacker to logonto the database with a valid username and password combination.--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 hashad all vendor supplied patches applied.--Contributors:Sourcefire Vulnerability Research TeamMatt Watchinski <mwatchinski@sourcefire.com>Brian Caswell <bmc@sourcefire.com>Nigel Houghton <nigel.houghton@sourcefire.com>Judy Novak <judy.novak@sourcefire.com>--Additional References:Bugtraqhttp://www.securityfocus.com/bid/9587Other:http://www.nextgenss.com/advisories/ora_time_zone.txt--
