Multiple vulnerabilities have been reported in Oracle Database, which can be exploited by malicious users to compromise a vulnerable system or conduct SQL injection attacks, and by malicious users and malicious people to disclose potentially sensitive information or to manipulate certain data.

1) An error in the Oracle Internet Directory component can be exploited to disclose or manipulate certain data.

For more information see vulnerability #1 in:
SA39439

2) An error in the Core RDBMS component can be exploited by authenticated users to execute arbitrary code.

3) An error in the XML DB component can be exploited by authenticated users to disclose or manipulate certain data.

4) Another error in the XML DB component can be exploited by authenticated users to disclose certain data.

5) Input passed to the "DROP_CHANGE_SOURCE" procedure within the "DBMS_CDC_PUBLISH PL/SQL" package in the "Data Capture" component is not properly sanitised before being used in an SQL query. This can be exploited to manipulate SQL queries by injecting arbitrary SQL code.

Successful exploitation allows execution of SQL statements with privileges of the SYS user, but requires authentication and "EXECUTE" permission on the "SYS.DBMS_CDC_PUBLISH" package.

6) An error in the Audit component can be exploited by authenticated users to manipulate certain data.

* Oracle Database 11g Release 2, version 11.2.0.1
* Oracle Database 11g Release 1, version 11.1.0.7
* Oracle Database 10g Release 2, versions 10.2.0.3 and 10.2.0.4
