It was discovered that nginx incorrectly handled CNAME response processing when the resolver is enabled. A remote attacker could use this issue to cause nginx to crash, resulting in a denial of service, or possibly execute arbitrary code. (CVE-2016-0746)

It was discovered that nginx incorrectly handled CNAME resolution when the resolver is enabled. A remote attacker could possibly use this issue to cause nginx to consume resources, resulting in a denial of service. (CVE-2016-0747)
