  Hello!

  Two security issues were identified in nginx HTTP/2 implementation,
  which might cause excessive memory consumption (CVE-2018-16843)
  and CPU usage (CVE-2018-16844).

  The issues affect nginx compiled with the ngx_http_v2_module (not
  compiled by default) if the "http2" option of the "listen" directive is
  used in a configuration file.

  The issues affect nginx 1.9.5 - 1.15.5.
  The issues are fixed in nginx 1.15.6, 1.14.1.

  Thanks to Gal Goldshtein from F5 Networks for initial report of the CPU
  usage issue.
