Description

The Call Blocker application 6.6.3 for Android incorrectly opens a key component that an attacker can use to inject large amounts of dirty data into the application&#39;s database. When the application starts, it loads the data from the database into memory. Once the attacker injects too much data, the application triggers an OOM error and crashes, resulting in a persistent denial of service.

Impact
