Synopsis

The remote FreeBSD host is missing a security-related update.

Description

Unbound reports :

We discovered a vulnerability in the processing of wildcard synthesized NSEC records. While synthesis of NSEC records is allowed by RFC4592, these synthesized owner names should not be used in the NSEC processing. This does, however, happen in Unbound 1.6.7 and earlier versions.

Solution

Update the affected package.
