"The remote MiracleLinux 4 host has packages installed that are affected by a vulnerability as referenced in the
AXSA:2016-137:02 advisory.

    Samba is the suite of programs by which a lot of PC-related machines
    share files, printers, and other information (such as lists of
    available files and printers). The Windows NT, OS/2, and Linux
    operating systems support this natively, and add-on packages can
    enable the same thing for DOS, Windows, VMS, UNIX of all kinds, MVS,
    and more. This package provides an SMB/CIFS server that can be used to
    provide network services to SMB/CIFS clients.
    Samba uses NetBIOS over TCP/IP (NetBT) protocols and does NOT
    need the NetBEUI (Microsoft Raw NetBIOS frame) protocol.
    Security issues fixed with this release:
    CVE-2015-7560
    The SMB1 implementation in smbd in Samba 3.x and 4.x before 4.1.23,
    4.2.x before 4.2.9, 4.3.x before 4.3.6, and 4.4.x before 4.4.0rc4
    allows remote authenticated users to modify arbitrary ACLs by using a
    UNIX SMB1 call to create a symlink, and then using a non-UNIX SMB1
    call to write to the ACL content.

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

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