+	<p>The OTP 29.0.6 release notes report:</p>
+	<blockquote cite="https://github.com/erlang/otp/releases/tag/OTP-29.0.6">
+	  <p>A gen_tcp socket using the inet driver and {packet,4} had
+	  a bug if receiving a packet with size just below INT_MAX.</p>
+	  <p>That packet size wrapped in size calculations and made the
+	  received data overwrite its allocation and trash allocator
+	  metadata and subsequent block(s), causing the VM to crash.</p>
+	  <p>This made it possible for anyone to remotely crash an
+	  Erlang node that used {packet,4} on a reachable socket.</p>
