+	<h1>Problem Description:</h1>
+	<p>Invoking SSL_read()/SSL_write() while in an error state
+	causes data to be passed without being decrypted/encrypted
+	directly from the SSL/TLS record layer.</p>
+	<p>In order to exploit this issue an application bug would
+	have to be present that resulted in a call to
+	SSL_read()/SSL_write() being issued after having already
+	received a fatal error. [CVE-2017-3737]</p>
+	<p>There is an overflow bug in the x86_64 Montgomery
+	multiplication procedure used in exponentiation with 1024-bit
+	moduli. This only affects processors that support the AVX2
+	but not ADX extensions like Intel Haswell (4th generation).
+	[CVE-2017-3738] This bug only affects FreeBSD 11.x.</p>
+	<h1>Impact:</h1>
+	<p>Applications with incorrect error handling may inappropriately
+	pass unencrypted data. [CVE-2017-3737]</p>
+	<p>Mishandling of carry propagation will produce incorrect
+	output, and make it easier for a remote attacker to obtain
+	sensitive private-key information. No EC algorithms are
+	affected and analysis suggests that attacks against RSA and
+	DSA as a result of this defect would be very difficult to
+	perform and are not believed likely.</p>
+	<p>Attacks against DH1024 are considered just feasible
+	(although very difficult) because most of the work necessary
+	to deduce information about a private key may be performed
+	offline. The amount of resources required for such an attack
+	would be very significant and likely only accessible to a
+	limited number of attackers. However, for an attack on TLS
+	to be meaningful, the server would have to share the DH1024
+	private key among multiple clients, which is no longer an
+	option since CVE-2016-0701. [CVE-2017-3738]</p>
