70% of Android Devices Vulnerable to a Remote Exploit
This should, in any other OS environment, not be possible to any large degree on a vulnerability patched some nine months ago. The danger comes from the structure of the Android ecosystem. One of its strengths is its open nature. This allows device manufacturers to both adopt and adapt the operating system for their own devices. But it also means that they, rather than Google, are responsible for software upgrades; and they are not very good at doing this.
