+	  <p>When parsing a frame header, validate that the frame_size is less than
+	or equal to INT32_MAX. Given frame_max is limited between 0 and
+	INT32_MAX in amqp_login and friends, this does not change the API.
+	This prevents a potential buffer overflow when a malicious client sends
+	a frame_size that is close to UINT32_MAX, in which causes an overflow
+	when computing state-&gt;target_size resulting in a small value there. A
+	buffer is then allocated with the small amount, then memcopy copies the
+	frame_size writing to memory beyond the end of the buffer.</p>
