CVE-2016-7426 (retired)

Priority
Description
NTP before 4.2.8p9 rate limits responses received from the configured
sources when rate limiting for all associations is enabled, which allows
remote attackers to cause a denial of service (prevent responses from the
sources) by sending responses with a spoofed source address.
