ASLR supposedly protects users from the Stagefright attack method because the RAM an app uses is never the same.īut the process is not perfect and nefarious attempts to circumvent ASLR are apparently already underway. The good news is that Google has clarified that, ever since Android 4.0 Ice Cream Sandwich, a technology known as Address Space Layout Randomizing (ASLR) has been a part of Android. More than 40 percent are running Jelly Bean or earlier. (KitKat also accounts for around 40 percent of users.) Only 18 percent of Android devices are running a version of Android Lollipop and less than three percent are using Android 5.1. This is how the Stagefright exploit works. This number, if you've taken a recent look at the percentages of different Android versions currently in use, is staggering. Stagefright could affect a billion devices, most particularly those running Android Jelly Bean or earlier.
