CVSS 3.0
7.8 highCVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:HCVE-2017-6451
High (7.8) in ntp ntp. EPSS 0.5% chance of exploitation in the next 30 days.
The mx4200_send function in the legacy MX4200 refclock in NTP before 4.2.8p10 and 4.3.x before 4.3.94 does not properly handle the return value of the snprintf function, which allows local users to execute arbitrary code via unspecified vectors, which trigger an out-of-bounds memory write.
