    Summary: Updated libssh packages fix CVE-2015-3146

    Details: Updated libssh packages fix security vulnerability: libssh versions 0.5.1 and above, but before 0.6.5, have a logical error in the handling of a SSH_MSG_NEWKEYS and SSH_MSG_KEXDH_REPLY package. A detected error did not set the session into the error state correctly and further processed the packet which leads to a null pointer dereference. This is the packet after the initial key exchange and doesn't require authentication. This could be used for a Denial of Service (DoS) attack (CVE-2015-3146).
