  package(s) announced via the referenced advisory.");

  script_tag(name:"vuldetect", value:"Checks if a vulnerable package version is present on the target host.");

  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.

  Patch Instructions:

  To install this openSUSE Security Update use the SUSE recommended
  installation methods
