Summary

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.

12.37% probability of exploitation in the next 30 days, higher than 96% of all scored CVEs.
