Subject: Oracle Advisory: Read parts of any file via
	desformat in Oracle Reports

Hello

3 months ago (15-april-2005) I informed the Oracle Security Team
(secalert_us@...cle.com) that I will publish bug details if the bugs are
not fixed with the next critical patch update (CPU July 2005). I know
that Oracle products are complex and a good patch quality need some
time. That's why I offered Oracle additional time if 3 months are not
sufficient for fixing the bugs. Oracle never asked for more time.

Oracle's behaviour not fixing critical security bugs for a long time
(over 650 days) is not acceptable for their customers. Oracle put their
customers in danger. At least one critical vulnerability can be abused
from any attacker via internet.

I decided to publish these vulnerabilities because it is possible to
mitigate the risk of these vulnerabilities by using the workarounds
provided in the advisories.

Kind Regards

Details
#######
Oracle Reports is Oracle's award-winning, high-fidelity enterprise
reporting
tool. It enables businesses to give immediate access to information to
all
levels within and outside of the organization in an unrivaled scalable
and
secure environment. Oracle Reports, a component of the Oracle
Application
Server, is used by Oracle itself for the E-Business Suite. Many large
customers are using Oracle Reports as reporting tool for their
enterprise applications.

The Oracle Reports parameter desformat can read any file by using an
absolute or relative file name.
Parts of the file content are displayed in the Reports error message
(see test case)

The DESFORMAT parameter specifies the format for the job output. In
bit-mapped environments, use DESFORMAT to specify the printer driver to
be used when DESTYPE is FILE. In character-mode environments, use it to
specify the
characteristics of the printer named in DESNAME.
