UltraJSON has an integer overflow handling large indent leads to buffer overflow or infinite loop
Summary ujson.dumps crashes the Python interpreter segmentation fault when the product of the indent parameter and the nested depth of the input exceeds INT32MAX. It can also get stuck in an infinite loop if the indent is a large negative number. Both are caused by an integer overflow/underflow...
