SUSE Linux Micro 6.0: 2025:20126-1 moderate: unbound DoS

## This update for unbound fixes the following issues: * Update to 1.22.0: Features: * Add iter-scrub-ns, iter-scrub-cname and max-global-quota configuration options. * Merge patch to fix for glue that is outside of zone, with `harden- unverified-glue`, from Karthik Umashankar (Microsoft). Enabling this option protects the Unbound resolver against bad glue, that is unverified out of zone glue, by resolving them. It uses the records as last resort if there is no other working glue. * Add redis-command-timeout: 20 and redis-connect-timeout: 200, that can set the timeout separately for commands and the connection set up to the redis server. If they are not specified, the redis-timeout value is used. * Log timestamps in ISO8601 format with timezone. This adds the option `log- time-iso: yes` that logs in ISO8601 format.
