Security issues fixed :

CVE-2019-9512: Fixed HTTP/2 flood using PING frames that results in
unbounded memory growth (bsc#1146111).

CVE-2019-9514: Fixed HTTP/2 implementation that is vulnerable to a
reset flood, potentially leading to a denial of service (bsc#1146115).

CVE-2019-14809: Fixed malformed hosts in URLs that leads to
authorization bypass (bsc#1146123).

Bugfixes: Update to go version 1.11.13 (bsc#1141688).

Note that Tenable Network Security has extracted the preceding
