Multiple vulnerabilities have been reported in various Oracle products. Some of these vulnerabilities have unknown impacts while others can be exploited to cause a DoS (Denial of Service), conduct cross-site scripting and SQL injection attacks, and potentially compromise the system.

Details are available for the following vulnerabilities:

1) Various input processed by the following packages is not properly sanitised before being used in SQL queries. This can be exploited to manipulate SQL queries by injecting arbitary SQL code:
* DBMS_XDBZ
* SDO_DROP_USER_BEFORE
* MD2
* DBMS_CDC_IMPDP
* DBMS_CDC_IPUBLISH
* DBMS_CDC_ISUBSCRIBE
* DBMS_SQLTUNE_INTERNAL
* SDO_GEOR_INT
* XDB_PITRIG_PKG
* SDO_DROP_USER
* SDO_CS
* SDO_LRS

2) Boundary errors in the RELATE functions of the MD2 and SDO_GEOM packages, the GEOM_OPERATION function of the SDO_3GL package, and the TRANSFORM_LAYER function of the SDO_CS package may be exploited to cause a buffer overflow.

3) Input passed to the WWV_FLOW_ITEM_HELP package, the NOTIFCATION_MSG parameter, the Oracle Reports "showenv", "parsequery", "cellwrapper", and "delimiter" parameters, and the "Expect" HTTP header is not properly sanitised before being returned to users. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of a vulnerable site.

4) An error allows a user with "create session" only privileges to update, delete, and insert via inline views.

Solution
Apply patches (see the vendor's advisory).
