CVE-2017-6451: High severity Apple macOS High Sierra vulnerability
ntp. Multiple issues were addressed by updating to version 4.2.8p10
Other sources
The mx4200send 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.
