"The remote MiracleLinux 4 host has packages installed that are affected by multiple vulnerabilities as referenced in the
AXSA:2017-2429:04 advisory.

    * A use-after-free flaw was found in the way samba servers handled certain SMB1 requests. An
    unauthenticated attacker could send specially-crafted SMB1 requests to cause the server to crash or
    execute arbitrary code. (CVE-2017-14746)
      * A memory disclosure flaw was found in samba. An attacker could retrieve parts of server memory, which
    could contain potentially sensitive data, by sending specially-crafted requests to the samba server.
    (CVE-2017-15275)
    Asianux would like to thank the Samba project for reporting these issues. Upstream acknowledges Yihan Lian
    and Zhibin Hu (Qihoo 360 GearTeam) as the original reporter of CVE-2017-14746; and Volker Lendecke (SerNet
    and the Samba Team) as the original reporter of CVE-2017-15275.
    CVE-2017-14746
    Use-after-free vulnerability in Samba 4.x before 4.7.3 allows remote
    attackers to execute arbitrary code via a crafted SMB1 request.
    CVE-2017-15275
    Samba before 4.7.3 might allow remote attackers to obtain sensitive
    information by leveraging failure of the server to clear allocated
    heap memory.

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.");
