ntpd in ntp before 4.2.8p3 with remote configuration enabled allows remote authenticated users with knowledge of the configuration password and access to a computer entrusted to perform remote configuration to cause a denial of service (service crash) via a NULL byte in a crafted configuration directive packet.

Security readout for executives and security teams

This issue can crash an NTP time service when remote configuration is enabled and an already trusted, authenticated remote user sends a malformed configuration directive. The business impact is availability: time synchronization could stop until the service is restarted or updated. The sources do not show public active exploitation. Exposure is likely limited to systems running ntp before 4.2.8p3 with remote configuration enabled. Systems without remote configuration, without trusted remote configuration clients, or already upgraded are less likely to be exposed based on the provided evidence. Treat this as a targeted availability risk, not a broad internet worm risk. Prioritize remediation on infrastructure where NTP availability supports authentication, logging, monitoring, or distributed systems, especially if remote configuration is enabled. Mitigation focus: Upgrade ntp to 4.2.8p3 or later where vendor packages are available.; Review Debian, Gentoo, Fedora, Red Hat, or relevant vendor advisories for package-specific fixes.; Disable remote configuration if it is not operationally required..
