"The remote MiracleLinux 4 host has packages installed that are affected by a vulnerability as referenced in the
AXSA:2017-1635:01 advisory.

    Libguestfs is a library for accessing and modifying guest disk images.
    Amongst the things this is good for: making batch configuration
    changes to guests, getting disk used/free statistics (see also:
    virt-df), migrating between virtualization systems (see also:
    virt-p2v), performing partial backups, performing partial guest
    clones, cloning guests and changing registry/UUID/hostname info, and
    much else besides.
    Libguestfs uses Linux kernel and qemu code, and can access any type of
    guest filesystem that Linux and qemu can, including but not limited
    to: ext2/3/4, btrfs, FAT and NTFS, LVM, many different disk partition
    schemes, qcow, qcow2, vmdk.
    Libguestfs provides ways to enumerate guest storage (eg. partitions,
    LVs, what filesystem is in each LV, etc.).  It can also run commands
    in the context of the guest.
    Libguestfs is a library that can be linked with C and C   management
    programs.
    For high level virt tools, guestfish (shell scripting and command line
    access), and guestmount (mount guest filesystems using FUSE), install
    'libguestfs-tools'.
    For shell scripting and command line access, install 'guestfish'.
    To mount guest filesystems on the host using FUSE, install
    'libguestfs-mount'.
    For Java bindings, install 'libguestfs-java-devel'.
    For OCaml bindings, install 'ocaml-libguestfs-devel'.
    For Perl bindings, install 'perl-Sys-Guestfs'.
    For Python bindings, install 'python-libguestfs'.
    For Ruby bindings, install 'ruby-libguestfs'.
    Security issues fixed with this release:
    CVE-2015-8869
    OCaml before 4.03.0 does not properly handle sign extensions, which
    allows remote attackers to conduct buffer overflow attacks or obtain
    sensitive information as demonstrated by a long string to the
    String.copy function.
    Additional Changes:

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
