+	<h1>Problem Description:</h1>
+	<p>Server or client applications that call the SSL_check_chain()
+	function during or after a TLS 1.3 handshake may crash due to a NULL
+	pointer dereference as a result of incorrect handling of the
+	"signature_algorithms_cert" TLS extension.  The crash occurs if an
+	invalid or unrecognized signature algorithm is received from the
+	peer.</p>
+	<h1>Impact:</h1>
+	<p>A malicious peer could exploit the NULL pointer dereference crash,
