In updateInternal of MediaProvider.java , there is a possible access of another app's files due to a missing permission check. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.
The product does not perform an authorization check when an actor attempts to access a resource or perform an action.
During installation, installed file permissions are set to allow anyone to modify those files.
