The remote Gentoo host is missing one or more security-related
The remote host is affected by the vulnerability described in GLSA-200908-02
(BIND: Denial of Service)
Matthias Urlichs reported that the dns_db_findrdataset() function fails
when the prerequisite section of the dynamic update message contains a
record of type 'ANY' and where at least one RRset for this FQDN exists
on the server.
A remote unauthenticated attacker could send a specially crafted
dynamic update message to the BIND daemon (named), leading to a Denial
of Service (daemon crash). This vulnerability affects all primary
(master) servers -- it is not limited to those that are configured to
allow dynamic updates.
Configure a firewall that performs Deep Packet Inspection to prevent
nsupdate messages from reaching named. Alternatively, expose only
secondary (slave) servers to untrusted networks.

All BIND users should upgrade to the latest version:

# emerge --ask --oneshot --verbose '>=net-dns/bind-9.4.3_p3'
