Reporting vulnerabilities

If you think you've found a vulnerability in a Microsoft product, you can help us and yourself by reporting it, either by email at secure@microsoft.com or by submitting the information at https://www.microsoft.com/technet/security/bulletin/alertus.aspx.

Vulnerabilities are a fact of life, though obviously one that all vendors strive to minimize. Good reporting helps minimize the window of opportunity for attackers to take advantage of vulnerabilities, so it's definitely appreciated.
