"The remote MiracleLinux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the
AXSA:2017-2064:04 advisory.

    The glibc package contains standard libraries which are used by
    multiple programs on the system. In order to save disk space and
    memory, as well as to make upgrading easier, common system code is
    kept in one place and shared between programs. This particular package
    contains the most important sets of shared libraries: the standard C
    library and the standard math library. Without these two libraries, a
    Linux system will not function.
    CVE-2014-9761
    Multiple stack-based buffer overflows in the GNU C Library (aka glibc
    or libc6) before 2.23 allow context-dependent attackers to cause a
    denial of service (application crash) or possibly execute arbitrary
    code via a long argument to the (1) nan, (2) nanf, or (3) nanl
    function.
    CVE-2015-8776
    The strftime function in the GNU C Library (aka glibc or libc6) before
    2.23 allows context-dependent attackers to cause a denial of service
    (application crash) or possibly obtain sensitive information via an
    out-of-range time value.
    CVE-2015-8777
    The process_envvars function in elf/rtld.c in the GNU C Library (aka
    glibc or libc6) before 2.23 allows local users to bypass a
    pointer-guarding protection mechanism via a zero value of the
    LD_POINTER_GUARD environment variable.
    CVE-2015-8778
    Integer overflow in the GNU C Library (aka glibc or libc6) before 2.23
    allows context-dependent attackers to cause a denial of service
    (application crash) or possibly execute arbitrary code via the size
    argument to the __hcreate_r function, which triggers out-of-bounds
    heap-memory access.
    CVE-2015-8779
    Stack-based buffer overflow in the catopen function in the GNU C
    Library (aka glibc or libc6) before 2.23 allows context-dependent
    attackers to cause a denial of service (application crash) or possibly
    execute arbitrary code via a long catalog name.
