Multiple vulnerabilities have been reported in Oracle Database, which can be exploited by malicious users to disclose potentially sensitive information, manipulate certain data, bypass certain security restrictions, conduct SQL injection attacks, cause a DoS (Denial of Service), and compromise a vulnerable system.
1) An unspecified error in the Application Express component can be exploited by authenticated users.
Successful exploitation of this vulnerability may allow execution of arbitrary code, but requires APEX developer user privileges.
2) Certain input passed via spatial indexes to the Core RDBMS 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 of this vulnerability requires Create session, create procedure, and create table privileges.
3) An error within the TABLEFUNC_ASOWN function in the Oracle Text component can be exploited by authenticated users to cause a buffer overflow via overly long string parameters.
Successful exploitation of this vulnerability requires Execute on CTXSYS.DRVDISP privileges.
4) An error within the OCIPasswordChange API in the Database Vault component can be exploited to change a user's password.
Successful exploitation of this vulnerability requires DV_ACCTMGR privileges.
5) An error within the OCIPasswordChange API in the Database Vault component can be exploited to change a user's password.
Successful exploitation of this vulnerability requires SYSDBA privileges.
