CVE-2016-8858: prevent resource depletion during key exchange (bsc#1005480)
CVE-2016-10009: limit directories for loading PKCS11 modules to avoid privilege escalation (bsc#1016366)
CVE-2016-10011: Prevent possible leaks of host private keys to low-privilege process handling authentication (bsc#1016369) Non security issues fixed :
Properly verify CIDR masks in the AllowUsers and DenyUsers configuration lists (bsc#1005893)
