ntpd in NTP before 4.2.8p7 and 4.3.x before 4.3.92 allows remote attackers to cause a denial of service (ntpd abort) by a large request data value, which triggers the ctl_getitem function to return a NULL value.

Security readout for executives and security teams

CVE-2016-2519 is a remote denial-of-service issue in ntpd. A crafted oversized request value can crash the NTP daemon, interrupting time synchronization. The main business risk is service reliability, not confirmed data theft or system takeover based on the supplied sources. Exposure is likely on systems running vulnerable ntpd versions, especially internet-reachable NTP services and downstream packages referenced by FreeBSD, Gentoo, Oracle, and NetApp advisories. The source bundle does not enumerate all affected products. Prioritize remediation for public or business-critical time services. This is not evidenced as a breach-enabling flaw, but ntpd crashes can disrupt authentication, logging, certificates, distributed systems, and incident timelines. Mitigation focus: Upgrade NTP to 4.2.8p7, 4.3.92, or later where applicable.; Apply operating system or appliance vendor updates for bundled ntpd packages.; Restrict NTP service exposure to trusted networks where operationally possible..
