libunbound2: A flaw was found in the way unbound before 1.6.8 validated wildcard-synthesized NSEC records
CVE-2017-15105 is fixed in 6 products on 1 platform, first by libunbound2 1.6.7-1ubuntu2.1, released January 22, 2018. It is not reported as exploited. Patch Radar priority: Routine.
A flaw was found in the way unbound before 1.6.8 validated wildcard-synthesized NSEC records. An improperly validated wildcard NSEC record could be used to prove the non-existence (NXDOMAIN answer) of an existing wildcard record, or trick unbound into accepting a NODATA proof.
