David,

Thank you for your answer.

That's not true. Or do you think that everything installed IN the database
is an Oracle database bug? Many Oracle and non-Oracle applications are
installing PL/SQL packages into the database, e.g. APEX, PORTAL, Reports,
SAP, ...  

Could you explain why PORTAL30.wwv_form.genpopuplist (CVE-2003-1193) is a
RDBMS bug but APEX.wwv_flow_utilities.gen_popup_list (CVE-2006-5351) is NOT
a database bug? 

Both are PL/SQL packages from an additional application (Portal vs.
APEX/HTMLDB) but the second bug is NOT covered in your paper.  

Whatever you say the numbers in your paper are not correct (too high or too
low) ;-). Probably you must add 35 APEX bugs to the next revision of your
paper. But at the moment the numbers are inconsistent.

DL> Again you're wrong. If you take another look at the link you

That's your opinion. If you read the advisory carefully you see that this
bug affects only installations with Oracle HTTP Server (OHS). Do you think
that soap.jar is part of the database or part of the HTTP Server? If HTTP is
not installed there was no problem. In 2004 Oracle used the a different
wording than 2006.

[... extract from advisory ...]
Required Conditions for Exploit
Access to SOAP enabled servers. Both XML and SOAP are installed by default
in Oracle9i
Application Server and Oracle9i Database Server when the Oracle HTTP Server
is installed.
[...]

Why is the SOAP bug covered by your paper but DB12-DB24 from CPU April 2005
(http://www.oracle.com/technology/deploy/security/pdf/cpuapr2005.pdf) are
not covered. DB12-DB24 e.g. are part of the Oracle HTTP Server but installed
by the some database installations.

Cheers,

 Alexander
