when authenticating non-existing users. A remote attacker could perform a
timing attack and enumerate valid users. (CVE-2016-6210)
Tomas Kuthan, Andres Rojas, and Javier Nieto discovered that OpenSSH did
not limit password lengths. A remote attacker could use this issue to cause
OpenSSH to consume resources, leading to a denial of service.
