+	    <li>When the truncated HMAC extension is enabled and CBC is used,
+	      sending a malicious application packet can be used to selectively
+	      corrupt 6 bytes on the peer's heap, potentially leading to a
+	      crash or remote code execution. This can be triggered remotely
+	      from either side in both TLS and DTLS.</li>
+	    <li>When RSASSA-PSS signature verification is enabled, sending a
+	      maliciously constructed certificate chain can be used to cause a
+	      buffer overflow on the peer's stack, potentially leading to crash
+	      or remote code execution. This can be triggered remotely from
