Multiple vulnerabilities have been reported in various Oracle products. Some of these vulnerabilities have unknown impacts, while others can be exploited to bypass certain security restrictions, gain knowledge of sensitive information, gain escalated privileges, cause a DoS (Denial of Service), conduct cross-site scripting and SQL injection attacks, or potentially compromise a vulnerable system..

Details are available for the following vulnerabilities:

1) The Oracle TNS Listener can be caused to shut down by sending a "TNS STOP" command to the Oracle Discoverer Servlet.

2) Input passed to the "expType" in search/admin/sources/boundary_rules.jsp in Oracle Secure Enterprise Search is not properly sanitised before being returned to the user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site.

3) Certain input processed by the following packages is not properly sanitised before being used in SQL queries. These can be exploited to manipulate SQL queries by injecting arbitrary SQL code:
* DBMS_APPLY_USER_AGENT
* DBMS_AQADM_SYS
* DBMS_CDC_PUBLISH
* DBMS_UPGRADE_INTERNAL
* APPS.ICXSUPWF.DisplayContacts

4) It is possible to bypass the Oracle database logon trigger.

5) Boundary errors within the DBMS_SNAP_INTERNAL package when processing SNAP_OWNER and SNAP_NAME parameters can be exploited to cause buffer overflows or to cause the Oracle server process to crash.

6) An error within the ADI_BINARY component of the E-Business Suite can be exploited to view or download documents in the APPS.FND_DOCUMENTS table.

7) An error within the APPLSYS.FND_DM_NODES package can be exploited to delete arbitrary Document Management nodes.

8) It is possible to gain DBA access when Simple File Sharing is enabled on Windows XP.

9) A race condition within the RLMGR_TRUNCATE_MAINT trigger can be exploited to gain escalated privileges.

10) Incorrect use of "SetSecurityDescriptorDacl()" can be exploited to execute arbitrary code with escalated privileges.

For more information:
SA24475

11) Missing authentication checks within the Oracle Intelligent Agent can be exploited to shut down the agent.

12) A boundary error within the DBMS_CDC_IPUBLISH package can be exploited to cause a stack-based buffer overflow via an overly long CHANGE_TABLE_NAME parameter.
