"According to its banner, the version of PHP running on the remote web
server is 7.0.x prior to 7.0.11. It is, therefore, affected by
multiple vulnerabilities :

  - An heap buffer overflow condition exists in the
    php_mysqlnd_rowp_read_text_protocol_aux() function
    within file ext/mysqlnd/mysqlnd_wireprotocol.c due to
    a failure to verify that a BIT field has the
    UNSIGNED_FLAG flag. An unauthenticated, remote attacker
    can exploit this, via specially crafted field metadata,
    to cause a denial of service condition. (CVE-2016-7412)

  - A use-after-free error exists in the
    wddx_stack_destroy() function within file
    ext/wddx/wddx.c when deserializing recordset elements.
    An unauthenticated, remote attacker can exploit this,
    via a specially crafted wddxPacket XML document, to
    cause a denial of service condition. (CVE-2016-7413)

  - An out-of-bounds access error exists in the
    phar_parse_zipfile() function within file ext/phar/zip.c
    due to a failure to ensure that the
    uncompressed_filesize field is large enough. An
    unauthenticated, remote attacker can exploit this, via a
    specially crafted archive, to cause a denial of service
    condition. (CVE-2016-7414)

  - A stack-based buffer overflow condition exists in the
    ICU4C library, specifically within file common/locid.cpp
    in the msgfmt_format_message() function, due to a
    failure to properly restrict the locale length provided
    to the Locale class. An unauthenticated, remote attacker
    can exploit this, via a long first argument to a
    MessageFormatter::formatMessage() function call, to
    cause a denial of service condition. (CVE-2016-7416)

  - A flaw exists in the spl_array_get_dimension_ptr_ptr()
    function within file ext/spl/spl_array.c due to a
    failure to properly validate the return value and data
    type when deserializing SplArray. An unauthenticated,
    remote attacker can exploit this, via specially crafted
    serialized data, to cause a denial of service condition.
    (CVE-2016-7417)

  - An out-of-bounds read error exists in the
    php_wddx_push_element() function within file
    ext/wddx/wddx.c when handling an incorrect boolean
    element, which leads to mishandling the
    wddx_deserialize() call. An unauthenticated, remote
    attacker can exploit this, via a specially crafted
    wddxPacket XML document, to cause a denial of service
    condition. (CVE-2016-7418)

  - An out-of-bounds access error exists in the
    phar_parse_tarfile() function within file ext/phar/tar.c
    when handling the verification of signatures. An
    unauthenticated, remote attacker can exploit this to
    cause an unspecified impact.");
