Descripción técnica

In Eclipse Vert.x versions [4.0.0, 4.5.35] or [5.0.0, 5.2.2], when a malicious server keeps sending bytes on an EOL-terminated line (not length-prefixed, for example a simple string [1]), we'll keep growing the buffer without bounds, eventually leading to an OOM. We need to have a configurable limit for EOL-terminated lines. If a malicious server sends a specially crafted RESP response (for example a bulk string [2] with missing CRLF trailer), the parser enters an infinite loop where it keeps parsing the same buffer and pushing the same response to the caller, which may lead e.g. to an OOM if the consumer just buffers the responses. We must fix the parser to avoid this infinite looping.
