"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)

  - CVE-2018-14056: path traversal in HTTP handler via ../
    in a web skin name. (bnc#1101280)

  - Update to version 1.7.0

  - Make ZNC UI translateable to different languages

  - Configs written before ZNC 0.206 can't be read anymore

  - Implement IRCv3.2 capabilities away-notify,
    account-notify, extended-join

  - Implement IRCv3.2 capabilities echo-message, cap-notify
    on the 'client side'

  - Update capability names as they are named in IRCv3.2:
    znc.in/server-time-iso→server-time,
    znc.in/batch→batch. Old names will continue working
    for a while, then will be removed in some future
    version.

  - Make ZNC request server-time from server when available

  - Add 'AuthOnlyViaModule' global/user setting

  - Stop defaulting real name to 'Got ZNC?'

  - Add SNI SSL client support

  - Add support for CIDR notation in allowed hosts list and
    in trusted proxy list

  - Add network-specific config for cert validation in
    addition to user-supplied fingerprints: TrustAllCerts,
    defaults to false, and TrustPKI, defaults to true.

  - Add /attach command for symmetry with /detach. Unlike
    /join it allows wildcards.

  - Update to version 1.6.6 :

  - Fix use-after-free in znc --makepem. It was broken for a
    long time, but started segfaulting only now. This is a
    useability fix, not a security fix, because self-signed
    (or signed by a CA) certificates can be created without
    using --makepem, and then combined into znc.pem.");
