Those of you that use Android devices will be interests, and perhaps horrified, to learn that a new exploit has been found by XDA Developers member alephzain. It is an exploit that has the potential to affect Samsung devices that are running on the Exynos 4210 and 4412 chips. This includes the Galaxy S3, Galaxy Note 2, Galaxy S2 and the Meizo MX.
The exploit opens up the physical memory and leaves it vulnerable to attack. Malicious apps would be able to enter and do untold damage to the device, including completely wiping all the data off it or can even ‘brick’ the device, rendering it completely useless. Even worse is that an attacker could silently access the users data and use it to their own advantage, without the user’s knowledge, or at least not until it is too late.
Information about the exploit has been passed to Samsung in the hopes that they can do something about it. However, one developer has already created a working APK and used it to root several Samsung devices just to show it can be done.
Any devices that use the Exynos 5 chip, such as the Nexus 10 will be unaffected and advice to other users is not to panic at the moment. There are no malicious apps as of yet that can make use of the exploit just yet and, with any luck, Samsung will fix it before this can happen. An unofficial and temporary fix is available and can be downloaded from Project Voodoo.
