Hello!

Several security issues were identified in nginx HTTP/2
implementation, which might cause excessive memory consumption
and CPU usage (CVE-2019-9511, CVE-2019-9513, CVE-2019-9516).

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 - 1.17.2.
The issues are fixed in nginx 1.17.3, 1.16.1.

Thanks to Jonathan Looney from Netflix for discovering these issues.
