Stack overflow error caused by progsbase serialization List

Description

progsbase before v0.4.0 was discovered to contain a stack overflow via the List parameter. This vulnerability allows attackers to cause a Denial of Service (DoS) via a crafted string.

Error Log

Exception in thread "main" java.lang.StackOverflowError

        list.add(list);
        JSONObjectWriter.writeJSON(list);
    }
}

Rectification Solution

  1. Refer to the solution of jackson-databind: Add the depth variable to record the current parsing depth. If the parsing depth exceeds a certain threshold, an exception is thrown. (FasterXML/jackson-databind@fcfc499)

  2. Refer to the GSON solution: Change the recursive processing on deeply nested arrays or JSON objects to stack+iteration processing.((google/gson@2d01d6a20f39881c692977564c1ea591d9f39027))

References

  1. If the value in map is the map's self, the new new JSONObject(map) cause StackOverflowError which may lead to dos jettison-json/jettison#52
