"The remote MiracleLinux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the
AXSA:2015-569:01 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.
    Security issues fixed with this release:
    CVE-2013-7423
    The send_dg function in resolv/res_send.c in GNU C Library (aka glibc
    or libc6) before 2.20 does not properly reuse file descriptors, which
    allows remote attackers to send DNS queries to unintended locations
    via a large number of request that trigger a call to the getaddrinfo
    function.
    CVE-2015-1472
    The ADDW macro in stdio-common/vfscanf.c in the GNU C Library (aka
    glibc or libc6) before 2.21 does not properly consider data-type size
    during memory allocation, which allows context-dependent attackers to
    cause a denial of service (buffer overflow) or possibly have
    unspecified other impact via a long line containing wide characters
    that are improperly handled in a wscanf call.
    CVE-2015-1473
    The ADDW macro in stdio-common/vfscanf.c in the GNU C Library (aka
    glibc or libc6) before 2.21 does not properly consider data-type size
    during a risk-management decision for use of the alloca function,
    which might allow context-dependent attackers to cause a denial of
    service (segmentation violation) or overwrite memory locations beyond
    the stack boundary via a long line containing wide characters that are
    improperly handled in a wscanf call.
    CVE-2015-1781
    Buffer overflow in the gethostbyname_r and other unspecified NSS
    functions in the GNU C Library (aka glibc or libc6) before 2.22 allows
    context-dependent attackers to cause a denial of service (crash) or
    execute arbitrary code via a crafted DNS response, which triggers a
    call with a misaligned buffer.
    Fixed bugs:
    These updated glibc packages also include numerous bug fixes and one enhancement.
