   An update that fixes two vulnerabilities is now available.

Description:

   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.
