CVE-2017-15105 Unbound vulnerability
Title: Unbound vulnerability
Summary: A security issue was fixed in Unbound.
Ralph Dolmans and Karst Koymans discovered that Unbound did not properly
handle certain NSEC records. An attacker could use this to to prove the
non-existence (NXDOMAIN answer) of an existing wildcard record, or trick
Unbound into accepting a NODATA proof.
Instructions: In general, a standard system update will make all the necessary changes.

CVE-2017-15105 unbound: Improper validation of wildcard synthesized NSEC records
A vulnerability was discovered in DNSSEC. Processing of wildcard synthesized NSEC records may result in improper validation for non-existance in some implementations of DNSSEC. While synthesis of NSEC records is allowed by RFC4592, the synthesized owner names should not be used in the NSEC processing.
