Buffer overflow in the password management functionality in NTP 4.2.x before 4.2.8p4, and 4.3.x before 4.3.77 allows remote authenticated users to cause a denial of service (daemon crash) or possibly execute arbitrary code via a crafted key file.
Does this matter?
EPSS puts the probability of exploitation in the next 30 days at 14.6%, higher than 97% of all known CVEs. Patch or mitigate before the next change window.
