	<p>Netty is a network application framework for development of protocol
	servers and clients. Prior to versions 4.1.135.Final and 4.2.15.Final,
	the HAProxy PROXY protocol v2 codec in netty leaks native or heap
	memory on every connection when a client sends a syntactically valid
	header containing nested `PP2_TYPE_SSL` TLVs (type-length-value
	records) at depth two or greater. The leak occurs on the successful
	parse path — no exception is thrown, the message fires downstream,
	the decoder removes itself, and the application releases the
	`HAProxyMessage` normally. Yet the underlying cumulation buffer (a
	pooled, potentially direct `ByteBuf` allocated by the channel) remains
	permanently pinned. Versions 4.1.135.Final and 4.2.15.Final patch the
	issue.</p>
