  CVE-2017-0898: Buffer underrun vulnerability in Kernel.sprintf
  If a malicious format string which contains a precious specifier (*)
    is passed and a huge minus value is also passed to the specifier,
    buffer underrun may be caused. In such situation, the result may
    contains heap, or the Ruby interpreter may crash.
  CVE-2017-10784: Escape sequence injection vulnerability in the Basic
    authentication of WEBrick
  When using the Basic authentication of WEBrick, clients can pass an
    arbitrary string as the user name. WEBrick outputs the passed user name
    intact to its log, then an attacker can inject malicious escape
    sequences to the log and dangerous control characters may be executed
    on a victim’s terminal emulator.
  This vulnerability is similar to a vulnerability already fixed, but
    it had not been fixed in the Basic authentication.
  CVE-2017-14033: Buffer underrun vulnerability in OpenSSL ASN1 decode
  If a malicious string is passed to the decode method of OpenSSL::ASN1,
    buffer underrun may be caused and the Ruby interpreter may crash.
  CVE-2017-14064: Heap exposure vulnerability in generating JSON
  The generate method of JSON module optionally accepts an instance of
    JSON::Ext::Generator::State class. If a malicious instance is passed,
    the result may include contents of heap.
