+	  <p>An attacker may cause an HTTP/2 endpoint to read arbitrary amounts
+	of header data by sending an excessive number of CONTINUATION frames.
+	Maintaining HPACK state requires parsing and processing all HEADERS
+	and CONTINUATION frames on a connection.  When a request&apos;s
+	headers exceed MaxHeaderBytes, no memory is allocated to store the
+	excess headers, but they are still parsed.  This permits an attacker
+	to cause an HTTP/2 endpoint to read arbitrary amounts of header
+	data, all associated with a request which is going to be rejected.
+	These headers can include Huffman-encoded data which is significantly
+	more expensive for the receiver to decode than for an attacker to
+	send.  The fix sets a limit on the amount of excess header frames
+	we will process before closing a connection.</p>
