+#
+# This is to fix a keyboard-interactive authentication brute force
+# vulnerability (MaxAuthTries bypass). A CVE number (CVE-2015-5600) has been
+# reserved for this problem, but not officially issued yet. This fix came from
+# OpenSSH upstream, which will be included in the future OpenSSH 7.0p1 release.
+# When we upgrade OpenSSH to 7.0 in the future, we will remove this patch.
