named in ISC BIND 9.x before 9.9.8-P4 and 9.10.x before 9.10.3-P4 does not properly handle DNAME records when parsing fetch reply messages, which allows remote attackers to cause a denial of service (assertion failure and daemon exit) via a malformed packet to the rndc (aka control channel) interface, related to alist.c and sexpr.c.

Affected: Ubuntu:14.04:LTS: bind9

It was discovered that Bind incorrectly handled input received by the rndc control channel. A remote attacker could possibly use this issue to cause Bind to crash, resulting in a denial of service. (CVE-2016-1285)

It was discovered that Bind incorrectly parsed resource record signatures for DNAME resource records. A remote attacker could possibly use this issue to cause Bind to crash, resulting in a denial of service. (CVE-2016-1286)
