GHSA-C38F-WX89-P2XG UltraJSON has a Memory Leak in ujson.dump() on Write Failure

Summary When ujson.dump writes to a file-like object and the write operation raises an exception, the serialized JSON string object is not decremented, leaking memory. Each failed write operation leaks the full size of the serialized payload. Code that uses ujson.dumps rather than ujson.dump or...
