  - A denial of service (DoS) vulnerability exists in the
    imagecreatefromgif and imagecreatefromstring functions
    of the gd_gif_in.c script within GD Graphics Library
    (libgd) due to an integer signedness error. An
    unauthenticated, remote attacker can exploit this issue,
    via a crafted GIF file, to cause the applicaiton to stop
    responding. (CVE-2018-5711)

  - A cross-site scripting (XSS) vulnerability exists due to
    improper validation of .phar file before returning it to
    users. An unauthenticated, remote attacker can exploit
    this, by convincing a user to click a specially crafted
    URL, to execute arbitrary script code in a user's browser
    session. (CVE-2018-5712)

  - A denial of service (DoS) vulnerability exists in the
    ext/standard/http_fopen_wrapper.c script due to
    http_header_value possibly being a NULL value in an atoi
    call. An unauthenticated, remote attacker can exploit
    this issue, via a specifically crafted HTTP response, to
    cause the application to stop responding. (CVE-2018-14884)
