The remote Gentoo host is missing one or more security-related
The remote host is affected by the vulnerability described in GLSA-200807-08
(BIND: Cache poisoning)
Dan Kaminsky of IOActive has reported a weakness in the DNS protocol
related to insufficient randomness of DNS transaction IDs and query
An attacker could exploit this weakness to poison the cache of a
recursive resolver and thus spoof DNS traffic, which could e.g. lead to
the redirection of web or mail traffic to malicious sites.
There is no known workaround at this time.

All BIND users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose '>=net-dns/bind-9.4.2_p1'
Note: In order to utilize the query port randomization to mitigate the
weakness, you need to make sure that your network setup allows the DNS
server to use random source ports for query and that you have not set a
fixed query port via the 'query-source port' directive in the BIND
