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.
