I haven't seen any information about this new local exploit for Microsoft Windows : http://www.haxorcitos.com/MSRC-6005bgs-EN.txt Description from Haxorcitos : As is Known, with the current Microsoft Security Model, applications that share the destkop are able to send messages between them. Every Desktop application is able to obtain the handle of every process executed in the same desktop. This feature and the possibility of any application to emulate a virtual keyboard by sending key strokes, allows every process to send messages and keys as if there were an interactive user.
This has been known for years and is the exact reason why Microsoft recommends that any service running with elevated privileges should *not* be run interactively [1]. This flaw allows for shatter attacks [2,3] and we have used it in [4] to attack personal firewalls.
