It appears, after all, that Microsoft doesn’t believe the FileTable security bug I described in a previous post (here) is By Design. The bug on Connect was Resolved as By Design a few weeks ago, but I didn’t agree.
So the upshot is that it will be fixed in a forthcoming update (presumably this means a Cumulative Update, although that wasn’t specified). If you are using FileTable, it would be best to keep an eye out for upcoming SQL Server 2012 updates and apply the one that addresses this issue as soon as possible.
