ntpd is vulnerable to arbitrary code execution. A buffer overflow flaw was discovered in the ntpd daemonβs NTPv4 authentication code. If ntpd was configured to use public key cryptography for NTP packet authentication, a remote attacker could use this flaw to send a specially-crafted request packet that could crash ntpd or, potentially, execute arbitrary code with the privileges of the βntpβ user.
