Samsung has just released an update for the Galaxy S3 which corrects a serious security vulnerability affecting multiple devices with processors Exynos 4210 or 4412.
A couple of weeks ago I mentioned about a serious security problem affecting several Samsung devices as the Galaxy S3, Galaxy S2, Galaxy Note 2, Galaxy Note 10.1, Galaxy Tab 7.7 and others. The exploit works on any device with a processor Exynos 4210 or 4412 and allows root access but leaves the devices vulnerable to attack. What happens is that the devices allow kernel code injections and RAM dumps of malware application that can be installed from Google Play Store, allowing malware applications to to obtain superuser privileges and root, easy access to the device’s physical memory and steal our data.
Samsung had announced that would correct this vulnerability “as soon as possible” and fortunately begun to do so, at least in its flagship. Several UK users are reporting that they have begun to receive a small update to Android 4.1.2 via OTA (firmware XXELLA), which fixes this vulnerability.
The Update is expected to reach the rest of the countries in the coming days and will be available for other affected devices soon. If you want to update your Galaxy S3 with the new firmware XXELLA and correct the vulnerabilities of your device now can do so by following our tutorial:
