Oracle 10g R2 and possibly other versions allows remote attackers to trigger internal errors, and possibly have other impacts, via an "alter session set events" command with invalid arguments. NOTE: this issue was originally disputed by a third party, but the dispute was retracted. NOTE: this issue was called an "integer overflow" in the original source, but this might be incorrect.

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.
