Sprint has released a new update for Galaxy Note 4 today which brings up the device from Android 5.0 to Android 5.1.1. Aside from bringing all of the improvements that are part and parcel of Android 5.1.1 this update also brings a critical security vulnerability fix. Sprint has patched the Stagefright vulnerability discovered in Android recently with this software update for the Galaxy Note 4.
The Stagefright vulnerability can allow hackers to exploit a phone using MMS as it targets Android’s Stagefright media handler component.
Hackers can send a video using MMS with the malicious code embedded, since the media handler automatically processes the video without requiring the user to open the MMS the malicious code runs and grants access to the device.
Data can then be stolen from the device and hackers can also gain access to the microphone and camera remotely, it goes without saying that this is a very critical vulnerability and it’s good to see that Sprint isn’t wasting any time in patching it.
Google has provided the fix to carriers and manufacturers while it’s going to send out security updates for Nexus devices in the coming days. The Galaxy Note 4 Android 5.1.1 update on Sprint also includes various bug fixes, performance improvements and a fix for the Message Waiting indicator.
