Subject : Correction to Microsoft Security Bulletin
MS99-025 (S-99-21) Date : 20-Jul-99
===============================================================================
By courtesy of MICROSOFT we received information on a correction to MS Security
Bulletin MS99-025: Unauthorized Access to IIS Servers through ODBC Data Access
with RDS.
CERT-NL recommends reading the advisory carefully.
==============================================================================
Microsoft Security Bulletin MS99-025
(http://www.microsoft.com/security/bulletins/MS99-025.asp ), which was
released on July 19, 1999, discussed a vulnerability associated with
Internet Information Server and Microsoft Data Access Components. The
Frequently Asked Questions (FAQ) page for this bulletin
(http://www.microsoft.com/security/bulletins/MS99-025faq.asp ) provided
instructions on how to manually change the registry in order to protect
vulnerable systems, and also provided an automated method for making the
changes. However, we have discovered that the automated method is
incorrect.
If you manually changed the registry entries as discussed in the bulletin,
you do not need to take any further action. All of the information in the
bulletin and FAQ regarding registry keys is correct. However, if you
downloaded HANDUNSF.REG and used it to automatically change the registry,
you should download the corrected file and run it on all affected systems.
The corrected file is named HANDSAFE.REG, in order to make it easy to tell
that you are using the right file. The file can be downloaded from the FAQ
page; the link to the file is contained in the answer to "I have MDAC 2.x
installed, what should I do?".
Even if you are not affected by this error, we recommend that you review the
FAQ page again. We have made a number of changes to the original version of
the FAQ, in order to provide a clearer description of the security
vulnerability and the steps that customers should take.
We regret the error and any inconvenience that it has caused. We are taking
steps to ensure that the problem will not happen again. Sincerely,
The Microsoft Product Security Team
