"It was discovered that the resolver in Bind made incorrect assumptions
about ordering when processing responses containing a CNAME or DNAME.
An attacker could use this cause a denial of service. (CVE-2017-3137)

Oleg Gorokhov discovered that in some situations, Bind did not
properly handle DNS64 queries. An attacker could use this to cause a
denial of service. (CVE-2017-3136)

Mike Lalumiere discovered that in some situations, Bind did not
properly handle invalid operations requested via its control channel.
An attacker with access to the control channel could cause a denial of
service. (CVE-2017-3138).

description block directly from the Ubuntu security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues.");
