More insights to CPU 12 April and public exploit code

Alex has just emailed me to say that he has updated his paper "Comments on Oracle Critical Patch Update April 2005" to include clarifications of the patch pre-requisites. He has also added links to Application Security Inc's advisories and also more importantly he has included three examples of exploits from Esteban Mart�nez Fay� site.

These include an exploit to grant DBA to SCOTT by PL/SQL Injecting DBMS_METADATA. This can be found at Also another exploit to grant DBA to SCOTT via the DBMS_CDC_SUBSCRIBE also by PL/SQL Injecting the package. This can be found at and finally sample Denial of Service attacks via Intermedia which can be found at

If you had not planned to apply this patch set quickly, you had better do so now!
