SoLive 1.6.14 thru 1.6.20 for Android has an exposed component that provides a method to modify the SharedPreference file. An attacker can leverage this method to inject a large amount of data into any SharedPreference file, which will be loaded into memory when the application is opened. When an attacker injects too much data, the application will trigger an OOM error and crash at startup, resulting in a persistent denial of service.
Weakness
During installation, installed file permissions are set to allow anyone to modify those files.

Potential Mitigations
- Compartmentalize the system to have “safe” areas where trust boundaries can be unambiguously drawn. Do not allow sensitive data to go outside of the trust boundary and always be careful when interfacing with a compartment outside of the safe area.
- Ensure that appropriate compartmentalization is built into the system design, and the compartmentalization allows for and reinforces privilege separation functionality. Architects and designers should rely on the principle of least privilege to decide the appropriate time to use privileges and the time to drop privileges.
