+	<blockquote cite="https://www.openssl.org/news/secadv/20211214.txt">
+	  <p>Invalid handling of X509_verify_cert() internal errors in libssl
+	    (Moderate)</p>
+	  <p>Internally libssl in OpenSSL calls X509_verify_cert() on the client
+	    side to verify a certificate supplied by a server. That function may
+	    return a negative return value to indicate an internal error (for
+	    example out of memory). Such a negative return value is mishandled by
+	    OpenSSL and will cause an IO function (such as SSL_connect() or
+	    SSL_do_handshake()) to not indicate success and a subsequent call to
+	    SSL_get_error() to return the value SSL_ERROR_WANT_RETRY_VERIFY.
+	    This return value is only supposed to be returned by OpenSSL if the
+	    application has previously called SSL_CTX_set_cert_verify_callback().
+	    Since most applications do not do this the
+	    SSL_ERROR_WANT_RETRY_VERIFY return value from SSL_get_error() will be
+	    totally unexpected and applications may not behave correctly as a
+	    result. The exact behaviour will depend on the application but it
+	    could result in crashes, infinite loops or other similar incorrect
+	    responses.</p>
