Are you the owner of a Samsung Galaxy S2, Galaxy S3, Galaxy Note 2, Note Galaxy 10.1, Galaxy Tab 7.7 and other devices with processors Exynos 4210 or 4412? Well then you should be careful because they just found a major security flaw that allows applications to steal your information.
The Android developer community has discovered a serious security problem that affects the Samsung Galaxy S3, Galaxy S2, Galaxy Note 2, certain Samsung tablets, the Meizu MX and other Lenovo devices. This exploit also works on any device that integrates the processor Exynos 4210 or 4412. But what does this exploit does? Makes it easy to gain root access but leaves the devices vulnerable to attack. According to XDA Alephzain, the developer who found the exploit, the devices allow kernel code injections and RAM dumps of malware application that can be installed from Google Play Store.
Ie the security breach allows malware applications to obtain root and superuser permissions, easy access to the device’s physical memory and thus have this access and steal our data.
Fortunately, the problem already is solved. Another XDA forum user called RyanZA has created a patch to modify these permissions on all affected devices. However, the only drawback is that users have confirmed that this freezes the camera on all devices. So far, Samsung has not issued any comment on this security flaw but hopefully they will soon do as there is great concern among users of these devices.
Meanwhile, the famous member Chainfire has released an APK that solves the problem with a patch and does not require root access (although it will be after using the application). Note that this may void your warranty but also makes your device more secure.
So now you know. If you have a Galaxy S2, Galaxy S3, Galaxy Note 2 or any other device with a processor Exynos 4210 or 4412, you need to be careful with what you download either from Google Play or outside of it. It is always advisable to read user comments before sending us to download something.
