"The remote Solaris system is missing necessary patches to address
security updates :

  - The default configuration of OpenSSH through 6.1
    enforces a fixed time limit between establishing a TCP
    connection and completing a login, which makes it easier
    for remote attackers to cause a denial of service
    (connection-slot exhaustion) by periodically making many
    new TCP connections. (CVE-2010-5107)

  - The auth_parse_options function in auth-options.c in
    sshd in OpenSSH before 5.7 provides debug messages
    containing authorized_keys command options, which allows
    remote authenticated users to obtain potentially
    sensitive information by reading these messages, as
    demonstrated by the shared user account required by
    Gitolite. NOTE: this can cross privilege boundaries
    because a user account may intentionally have no shell
    or filesystem access, and therefore may have no
    supported way to read an authorized_keys file in its own
    home directory. (CVE-2012-0814)"
