Last modified

CVE-2015-5219 is a high-severity vulnerability rated 7.5/10 on the CVSS scale. The ULOGTOD function in ntp.d in SNTP before 4.2.7p366 does not properly perform type conversions from a precision value to a double, which allows remote attackers to cause a denial of service (infinite loop) via a crafted NTP packet.. EPSS estimates a 5.89% chance of exploitation in the next 30 days.
