Hello! The Microsoft Security Response Center investigates all reports of security vulnerabilities sent to us that affect Microsoft products. If you believe you have found a security vulnerability affecting a Microsoft product, we would like to work with you to investigate it. We are concerned that people might not know the best way to report security vulnerabilities to Microsoft. You can contact the Microsoft Security Response Center to report a vulnerability by emailing secure@xxxxxxxxxxxxx directly, or you can submit your report via our web-based vulnerability reporting form located at: https://www.microsoft.com/technet/security/bulletin/alertus.aspx Sincerely, Microsoft Security Response Center
