Stack-based buffer overflow in Oracle Net Services for Oracle Database Server 9i release 2 and earlier allows attackers to execute arbitrary code via a "CREATE DATABASE LINK" query containing a connect string with a long USING parameter.

Oracle Database 9i and 10g disables Fine Grained Audit (FGA) after the SYS user executes a SELECT statement on an FGA object, which makes it easier for attackers to escape detection.

SQL injection vulnerability in the (1) MDSYS.SDOGEOMTRIGINS1 and (2) MDSYS.SDOLRSTRIGINS default triggers in Oracle 9i and 10g allows remote attackers to execute arbitrary SQL commands via the new.tablename or new.columnname parameters.

The triggers in Oracle 9i and 10g allow local users to gain privileges by using a sequence of partially privileged actions: using CCBKAPPLROWTRIG or EXECCBKFNDML to add arbitrary functions to the SDOCMTDBKFNTABLE and SDOCMTCBKDMLTABLE, then performing a DELETE on the SDOTXNIDXINSERTS table, which causes the SDOCMTCBKTRIG trigger to execute the user-supplied functions.
