"The remote MiracleLinux 4 host has packages installed that are affected by multiple vulnerabilities as referenced in the
AXSA:2016-145:01 advisory.

    SSH (Secure SHell) is a program for logging into and executing
    commands on a remote machine. SSH is intended to replace rlogin and
    rsh, and to provide secure encrypted communications between two
    untrusted hosts over an insecure network. X11 connections and
    arbitrary TCP/IP ports can also be forwarded over the secure channel.
    OpenSSH is OpenBSD's version of the last free version of SSH, bringing
    it up to date in terms of security and features.
    This package includes the core files necessary for both the OpenSSH
    client and server. To make this package useful, you should also
    install openssh-clients, openssh-server, or both.
    Security issues fixed with this release:
    CVE-2015-5600
    The kbdint_next_device function in auth2-chall.c in sshd in OpenSSH
    through 6.9 does not properly restrict the processing of
    keyboard-interactive devices within a single connection, which makes
    it easier for remote attackers to conduct brute-force attacks or cause
    a denial of service (CPU consumption) via a long and duplicative list
    in the ssh -oKbdInteractiveDevices option, as demonstrated by a
    modified client that provides a different password for each pam
    element on this list.
    CVE-2016-3115
    ** RESERVED **
    This candidate has been reserved by an organization or individual that
    will use it when announcing a new security problem.  When the
    candidate has been publicized, the details for this candidate will be
    provided.

Tenable has extracted the preceding description block directly from the MiracleLinux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
number.");
