How about:

As of version 1.5.13, the Cygwin developers are not aware of any feature
in the cygwin dll that would allow users to gain privileges or to access
objects to which they have no rights under Windows. However there is no
guarantee that Cygwin is as secure as the Windows it runs on.
Cygwin processes share some variables and are thus easier targets of
denial of service type of attacks.
