CVE-2017-3136 — An error handling synthesized records could cause an assertion failure when using DNS64 with "break-dnssec yes;"

Affected: ISC BIND 9

A query with a specific set of characteristics could cause a server using DNS64 to encounter an assertion failure and terminate. An attacker could deliberately construct a query, enabling denial-of-service against a server if it was configured to use the DNS64 feature and other preconditions were met. Affects BIND 9.8.0 -> 9.8.8-P1, 9.9.0 -> 9.9.9-P6, 9.9.10b1->9.9.10rc1, 9.10.0 -> 9.10.4-P6, 9.10.5b1->9.10.5rc1, 9.11.0 -> 9.11.0-P3, 9.11.1b1->9.11.1rc1, 9.9.3-S1 -> 9.9.9-S8.

USN-3259-1 — bind9 vulnerabilities

Affected: Ubuntu:14.04:LTS: bind9, Ubuntu:16.04:LTS: bind9

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)
