+	<blockquote cite="https://github.com/erlang/otp/releases/tag/OTP-28.5.0.5">
+	  <p>The SSH client and server now reject incoming packets not
+	  aligned to the cipher block size as required by RFC 4253
+	  section 6. For CBC ciphers, a timing-safe "packet discard"
+	  mechanism (CVE-2008-5161 mitigation) ensures structural errors
+	  are indistinguishable from MAC failures before disconnecting.
+	  AEAD and encrypt-then-MAC modes disconnect immediately.</p>
