Description:
9
 
 A flaw was found in the way unbound before 1.6.8 validated
10
 
 wildcard-synthesized NSEC records. An improperly validated wildcard NSEC
11
 
 record could be used to prove the non-existence (NXDOMAIN answer) of an
12
 
 existing wildcard record, or trick unbound into accepting a NODATA proof.

Ubuntu-Description:
14
 
 Ralph Dolmans and Karst Koymans discovered that Unbound did not
15
 
 properly handle certain NSEC records. An attacker could use this to
16
 
 to prove the non-existence (NXDOMAIN answer) of an existing wildcard
17
 
 record, or trick Unbound into accepting a NODATA proof.
