openSUSE Security Update : znc (openSUSE-2018-819)
Medium Nessus Plugin ID 111584
SynopsisThe remote openSUSE host is missing a security update.
DescriptionThis 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.
SolutionUpdate the affected znc packages.
