Microsoft Security Advisory (921923)
Proof of Concept Code Published Affecting the Remote Access Connection Manager Service
Microsoft is aware that detailed exploit code has been published on the Internet for the vulnerability that is addressed by Microsoft security bulletin MS06-025. Microsoft is not currently aware of active attacks that use this exploit code or of customer impact at this time. However, Microsoft is actively monitoring this situation to keep customers informed and to provide customer guidance as necessary.
Our investigation of this exploit code has verified that it does not affect customers who have installed the updates detailed in MS06-025 on their computers. Microsoft continues to recommend that customers apply the updates to the affected products by enabling the Automatic Updates feature in Windows.
Microsoft is disappointed that certain security researchers have breached the commonly accepted industry practice of withholding vulnerability data so close to update release and have published exploit code, potentially harming computer users. We continue to urge security researchers to disclose vulnerability information responsibly and allow customers time to deploy updates so they do not aid criminals in their attempt to take advantage of software vulnerabilities
