Vulnerability Title
LockScreenSettings - Theft arbitrary files with system privilege
Source: NVD (National Vulnerability Database)
Vulnerability Description
The vulnerability is to theft of arbitrary files with system privilege in the LockScreenSettings ("com.lge.lockscreensettings") app in the "com/lge/lockscreensettings/dynamicwallpaper/MyCategoryGuideActivity.java" file. The main problem is that the app launches implicit intents that can be intercepted by third-party apps installed on the same device. They also can return arbitrary data that will be passed to the "onActivityResult()" method. The LockScreenSettings app copies the received file to the "/data/shared/dw/mycategory/wallpaper_01.png" path and then changes the file access mode to world-readable and world-writable.
