I will post detailed information including sample code on my blog tomorrow. Especially the dbms_sys_sql bug is critical because it allows to bypass the Oracle Auditing completely (and products using Oracle Auditing like Oracle Audit Vault). Even if this bug is fixed now there are other (similar) bugs around which allow to bypass Oracle Auditing completely.
It took only approx. 2 years to fix the dbms_sys_sql problem.
