Multiple vulnerabilities have been reported for various Oracle products. Some have unknown impacts, others can be exploited to disclose sensitive information, conduct SQL injection attacks, to cause a DoS (Denial of Service), or to compromise a vulnerable system.

Details are available for the following vulnerabilities:

1) An input validation error exists within the GIOP service in Oracle TNS Listener when processing connect GIOP packets. This can be exploited to crash the TNS Listener or to disclose potential sensitive information via a specially crafted packet.

2) Certain input processed by the CTX_DOC package is not properly sanitised before being used in SQL queries. This can be exploited to manipulate SQL queries by injecting arbitrary SQL code via the THEMES, GIST, TOKENS, FILTER, HIGHLIGHT, and MARKUP procedures.

3) An error in Oracle RDBMS when processing TNS data packets can be exploited to cause high CPU usage via a specially crafted packet sequence.

4) Certain input processed by the LT package is not properly sanitised before being used in SQL queries in the FINDRICSET package. This can be exploited to manipulate SQL queries by injecting arbitrary SQL code via the FINDRICSET procedure.

Successful exploitation of this vulnerability allows an attacker to gain "SYS" privileges.

5) An error in the Oracle XML DB ftp service leads to incorrect "USERID" entries in the audit trail.

6) A Boundary error in the DBLINK_INFO procedure within the DBMS_AQADM_SYS package can be exploited by users with EXECUTE privileges to cause a buffer overflow.

7) A boundary error in the TRANSFORM procedure within the MDSYS.SDO_CS package can be exploited to cause a buffer overflow.

Successful exploitation of vulnerabilities #6 and #7 allows crashing the Oracle process or execution of arbitrary code, but requires valid user credentials.

8) Certain input passed to the okxLOV.jsp page in the Administration console of Oracle E-Business Suite is not properly sanitised before being used in SQL queries. This can be exploited to manipulate SQL queries by injecting arbitrary SQL code in the context of the "APPS" user.
