HIGH7.5

The ULOGTOD function in ntp

Published Jul 21, 2017

Modified 1 years ago

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.
