Microsoft Tuesday reissued one of the dozen June security bulletins with updated patches to fix flaws in the original that broke dial-up functionality for some users.

MS06-025, which goes by the title "Vulnerability in Routing and Remote Access Could Allow Remote Code Execution," was re-released late Tuesday with refreshed patches. Not everyone will need to install this updated update, however.

"If you are not affected by any of these scenarios or have installed the original update without any issues then you should not be impacted by the re-release," wrote Adrian Stone of the Microsoft Security Response Center on the MSRC's blog.

Microsoft also published an updated support document to account for the changes.

The MS06-025 update was first released two weeks ago as part of a record-setting security update, and patched a pair of critical bugs in Windows' Routing and Remote Access service. Within days, users and security professionals began reporting problems with dial-up connections via terminals or dial-up scripting. Microsoft quickly committed to re-releasing the patch.

This is the second time in the last three months that Microsoft has been forced to patch an update. In April, the Redmond, Wash. developer re-released a fix to eliminate a slew of bad behaviors that the original caused on systems running older Hewlett-Packard software or NVIDIA graphics drivers.
