"According to the versions of the php packages installed, the EulerOS
installation on the remote host is affected by the following
vulnerabilities :

  - In PHP through 5.6.33, 7.0.x before 7.0.28, 7.1.x
    through 7.1.14, and 7.2.x through 7.2.2, there is a
    stack-based buffer under-read while parsing an HTTP
    response in the php_stream_url_wrap_http_ex function in
    ext/standard/http_fopen_wrapper.c. This subsequently
    results in copying a large string.(CVE-2018-7584)

  - In PHP before 5.5.32, 5.6.x before 5.6.18, and 7.x
    before 7.0.3, all of the return values of
    stream_get_meta_data can be controlled if the input can
    be controlled (e.g., during file uploads). For example,
    a '$uri = stream_get_meta_data(fopen($file,
    'r'))['uri']' call mishandles the case where $file is
    data:text/plainuri=eviluri, -- in other words, metadata
    can be set by an attacker.(CVE-2016-10712)

  - The GIF decoding function gdImageCreateFromGifCtx in
    gd_gif_in.c in the GD Graphics Library (aka libgd), as
    used in PHP before 5.6.31 and 7.x before 7.1.7, does
    not zero colorMap arrays before use. A specially
    crafted GIF image could use the uninitialized tables to
    read ~700 bytes from the top of the stack, potentially
    disclosing sensitive information.(CVE-2017-7890)
