Detailed vulnerability description
The vulnerability allows a local attacker to execute arbitrary code on the target system.
The weakness exists due to improper handling of the return value of the snprintf function by the mx4200_send function in the legacy MX4200 refclock in NTP. A local attacker can trigger out-of-bounds memory write and execute arbitrary code with root privileges.
Successful exploitation of the vulnerability may result in system compromise.
