+	  <p>A memory corruption vulnerability exists in the post-
+	    authentication sshd process when an AES-GCM cipher
+	    (aes128-gcm@openssh.com or aes256-gcm@openssh.com) is
+	    selected during kex exchange.
+
+	    If exploited, this vulnerability might permit code execution
+	    with the privileges of the authenticated user and may
+	    therefore allow bypassing restricted shell/command
+	    configurations.</p>
+	  <p>Either upgrade to 6.4 or disable AES-GCM in the server
+	    configuration. The following sshd_config option will disable
+	    AES-GCM while leaving other ciphers active:
+
+	    Ciphers aes128-ctr,aes192-ctr,aes256-ctr,aes128-cbc,3des-cbc,blowfish-cbc,cast128-cbc,aes192-cbc,aes256-cbc
