This update for znc fixes the following issues:

– Update to version 1.7.1
* CVE-2018-14055: non-admin user could gain admin privileges and shell
access by injecting values into znc.conf (bnc#1101281)

* Configs written before ZNC 0.206 can’t be read anymore
* Implement IRCv3.2 capabilities away-notify, account-notify,
* Implement IRCv3.2 capabilities echo-message, cap-notify on the “client
* Update capability names as they are named in IRCv3.2:→server-time,→batch. Old names

* Fix use-after-free in znc –makepem. It was broken for a long time,

be created without using –makepem, and then combined into znc.pem.
