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.

1) Two boundary errors exist in the XDB.XDB_PITRIG_PKG.PITRIG_TRUNCATE and XDB.XDB_PITRIG_PKG.PITRIG_DROP procedures. These can be exploited to cause buffer overflows via overly long arguments passed to the affected procedures.

2) Input passed via the first argument to the XDB.XDB_PITRIG_PKG.PITRIG_TRUNCATE and XDB.XDB_PITRIG_PKG.PITRIG_DROP procedures is not properly sanitised before being used in SQL queries. This can be exploited to manipulate an SQL query by injecting arbitrary SQL code.

3) An error within the implementation of the Ultra-Search module can be exploited to bypass security restrictions due to unnecessary high privileges assigned to the WKSYS user account and database schema.

Successful exploitation of the vulnerability requires WKSYS access.

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