VulnerabilityModified
CVE-2016-0747
The resolver in nginx before 1.8.1 and 1.9.x before 1.9.10 does not properly limit CNAME resolution, which allows remote attackers to cause a denial of service (worker process resource consumption) via vectors related to arbitrary name resolution.

Does this matter?
Lower severity and a low EPSS score (8.43%). Track it; it rarely justifies an emergency change on its own.
