Upgrade SLES:15.7 unbound-python to version 1.26.1-150600.23.24.1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream unbound-python package and not the unbound-python package as distributed by SLES. See How to fix? for SLES:15.7 relevant fixed versions and status.

In NLnet Labs Unbound 1.7.0 up to and including 1.25.1, when an auth/rpz zone has a configured primary hostname that resolves to BOGUS A/AAAA, it is still considered as a possible XFR endpoint. A malicious actor that can spoof the hostname's A/AAAA record (no valid RRSIG required) becomes the zone's XFR primary and can replaces the entire zone/the resolver's entire response policy.
