Dear Microsoft Customer – The Microsoft Security Response Center has learned of a security vulnerability affecting a software component used only by members of certain Microsoft customer programs.  You’ve received this mail because you have registered as a member of one of the programs and may have come in contact with the component that contains the vulnerability.  Microsoft believes that only a small number of customers actually are at risk, but we do urge you to use the following information to ensure that your system is secure. The vulnerability could enable an attacker to gain control over another user’s system.  It lies in a software component called the File Transfer Manager (FTM), the purpose of which is to allow members of Microsoft beta programs, MSDN, Microsoft Volume Licensing Services, and a small number of other Microsoft programs to download software from certain Microsoft sites.  The FTM is only distributed through these programs, but not every member has installed it.  Even among customers who have installed it, not all are at risk, as only certain versions contain the vulnerability.
