"The remote MiracleLinux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the
AXSA:2017-2305:06 advisory.

    * It was found that samba did not enforce SMB signing when certain configuration options were enabled. A
    remote attacker could launch a man-in-the-middle attack and retrieve information in plain-text.
    (CVE-2017-12150)
      * A flaw was found in the way samba client used encryption with the max protocol set as SMB3. The
    connection could lose the requirement for signing and encrypting to any DFS redirects, allowing an
    attacker to read or alter the contents of the connection via a man-in-the-middle attack. (CVE-2017-12151)
      * An information leak flaw was found in the way SMB1 protocol was implemented by Samba. A malicious
    client could use this flaw to dump server memory contents to a file on the samba share or to a shared
    printer, though the exact area of server memory cannot be controlled by the attacker. (CVE-2017-12163)
    Asianux would like to thank the Samba project for reporting CVE-2017-12150 and
    CVE-2017-12151 and Yihan Lian and Zhibin Hu (Qihoo 360 GearTeam), Stefan
    Metzmacher (SerNet), and Jeremy Allison (Google) for reporting CVE-2017-12163.
    Upstream acknowledges Stefan Metzmacher (SerNet) as the original reporter of
    CVE-2017-12150 and CVE-2017-12151.
