Summary:

Gson could be made to crash if it opened a specially crafted
file.

Software Description:
- libgoogle-gson-java: A Java serialization/deserialization library to convert 
Java Objects into JSON and back

Details:

It was discovered that Gson incorrectly handled deserialization of untrusted
