概要
Nest: DoS via Recursive handleData in JsonSocket (TCP Transport)
原文の説明
取得元が公開している説明をそのまま載せています (多くは英語)。
Nest is a framework for building scalable Node.js server-side applications. Prior to 11.1.19, when an attacker sends many small, valid JSON messages in one TCP frame, handleData() recurses once per message; the buffer shrinks each call. maxBufferSize is never reached; call stack overflows instead. A ~47 KB payload is sufficient to trigger RangeError. This vulnerability is fixed in 11.1.19.
