Multiple vulnerabilities have been reported for various Oracle products. Some vulnerabilities have unknown impacts while others can be exploited by malicious users to bypass certain security restrictions, conduct SQL injection attacks, cause a DoS (Denial of Service), or potentially compromise a vulnerable system, and potentially by malicious people to hijack a user session.

1) Input passed via unspecified parameters to the SDO_GEOM, SDO_IDX, and SDO_UTIL packages is not properly sanitised before being used in SQL queries. This can be exploited to manipulate SQL queries by injecting arbitrary SQL code.

2) The problem is that the DBMS_STATS_INTERNAL package resets the OUTLN password to a default value and grants DBA privileges to the OUTLN user during the creation of a materialized view.

3) An error within the "flows_030000.wwv_execute_immediate.run_ddl()" function included in Oracle Application Express can be exploited to execute SQL commands with escalated privileges.

Successful exploitation requires access to the "flows_030000.wwv_execute_immediate.run_ddl()" function (e.g. the WMSYS, WKSYS, FLOWS_030000, and OUTLN accounts by default).

4) An error exists in the implementation of the "Direct Path" export mode. This can be exploited to extract data from restricted tables via the "0x5B" TNS protocol message.

NOTE: Reportedly, the vulnerability cannot be exploited to access SYS schema objects.

5) The problem is that the "www_flow_user2" cookie is not invalidated when a user logs off and can potentially be exploited to hijack a valid session.

6) Input passed via unspecified parameters to the DBMS_CDC_UTILITY package is not properly sanitised before being used in SQL queries. This can be exploited to manipulate SQL queries by injecting arbitrary SQL code.

Successful exploitation requires EXECUTE privileges on the SYS.DBMS_CDC_UTILITY package.

7) A boundary error in the GET_FULL_FILENAME procedure within the SYS.KUPF$FILE_INT package can be exploited cause a buffer overflow.

Successful exploitation may allow execution of arbitrary code, but requires EXECUTE privileges on the SYS.KUPF$FILE_INT package.

8) A boundary error in the AQ$_REGISTER and AQ$_UNREGISTER procedures within the SYS.DBMS_AQJMS_INTERNAL package can be exploited to cause a buffer overflow.

Successful exploitation may allow execution of arbitrary code, but requires EXECUTE privileges on the SYS.DBMS_AQJMS_INTERNAL package.

The remaining vulnerabilities are caused due to unspecified errors. No more information is currently available.
