Amazingly good bad event
It's actually amazing to me. These guys closed up an exploit that is preventing this vendor from doing exactly what their users "clients" hired them to do. Spy on someone else's phone by installing some app on it.
The fact this hole is caught and fixed. This is a high bar of security and good to see I think. Almost scary, but if we simply don't have any "spyware" available because of tight security, I think the world can live with that. (If anything, mirroring and other types of administrative controls should be coming in centrally through the front door only on devices that are purposely built around nanny ware or corporate infrastructure that converts devices to more of a "kiosk" where users are not meant to be trusted.)
Simply installing a random app almost CANNOT compromise your phone. I suppose that is good news? I am a little scared by the Palladium / Right to Read / "trusted developer" model, but if I am free to side-load apps on Android via *.apk files and even root my android phone IF I WANT TO, then I suppose the balance that should exists.
Amazingly tight security Apple and Google (and this third party guy). Keep it up, you're even working together on this. These are amazing times.
