abc3ef37-95d4-11ea-9004-25fadb81abf4json-c -- integer overflow and out-of-bounds write via a large JSON file

Tobias Stöckmann reports:

I have discovered a way to trigger an out of boundary write while parsing a huge json file through a malicious input source. It can be triggered if an attacker has control over the input stream or if a huge load during filesystem operations can be triggered.
