Detailed vulnerability description

The vulnerability allows a remote non-authenticated attacker to perform a denial of service (DoS) attack.

In getOffsetForHorizontal of Layout.java, there is a possible application hang due to a slow width calculation. This could lead to remote denial of service if a contact with many hidden unicode characters were sent to the device and used by a local app, with no additional execution privileges needed.
