Not just that.. its already reasonably moot.
"First, a patch been sent to OEMs and AOSP, but with Android's abysmal update situation, this is a moot point. The crux, however, lies with Google Play and Verify Apps. These have already been updated to detect this issue, and prevent applications that try to abuse this flaw from being installed"
Google reacted to this disclosure rapidly and well.
Of course such a vulnerability would probably never be FOUND in iOS or WinPhone, since they are closed source, and almost certainly never disclosed if it was.
Just update your play store, and you are safe unless you are sideloading (never a great idea)
If you are sideloading then if you leave verify apps on, its also no problem.
Google are also scanning all apps on Google Play to check no one has been trying this.
Yawn, another google/Android beatup trying to wag the dog. Not hard to guess where the spin is originating.
