A remote attacker could perform a\ntiming attack and enumerate valid users. (CVE-2016-6210)\n\nTomas Kuthan, Andres Rojas, and Javier Nieto discovered that OpenSSH did\nnot limit password lengths. A remote attacker could use this issue to cause\nOpenSSH to consume resources, leading to a denial of service.\n(CVE-2016-6515)\n",
