TL;DR

TJSONProtocol.readJSONString decodes a JSON string from the transport with no length limit. A peer can send one enormous string and force the process to allocate without bound while reading a message. The fix enforces a default string-length limit during string decoding.

Who does this affect?

You are affected if you are using a version that falls within the vulnerable range and you deserialize untrusted Thrift JSON messages.
