Google plans to release Android N a solution to prevent new vulnerabilities expose both the system as well as seen in the famous bug Stagefright. The MediaServer feature compactor present from early versions of Android and recurrent attacks target will be modified to prevent the deep hacker attack
Although the providence of details are a bit technical, are not difficult to understand.: Google wants to divide the MediaServer, responsible for compressing image files, video and audio to deliver more performance to the user in various subcategories, each in charge of a smaller and more specific task.
Instead of a single media server, the new Android will separate servers dedicated camera data compression, another for audio, a third for codecs, and so against. The result is a fragmentation of a previously unified function, preventing malicious code from spreading easily.
The aim is to ensure that if any attack, the impact is minimal to the user. Google hopes that with the division of tasks, even a compromised smartphone is relatively safe, since the criminal would have access to a limited number of permissions – before gaining access to the full MediaServer allow the hacker to take control of many machine functions at once
According to the Android documentation N:.
This means that a committed libstagefright grant the attacker access to a significantly smaller number of permissions and also prevents him get more privileges to reduce the attack surface exposed by the kernel.
Android N should have the name revealed during the Google I / O conference that takes place between 18 and May 20 in Mountain View, California, USA. At the time, Google engineers should also introduce other new system, including security enhancements. Currently, the test version is the third version, and should go to the Preview 5 before arriving at the final product.
