script_tag(name:"insight", value:"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 usability 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.
