ntpd in NTP 4.2.x before 4.2.8p4, and 4.3.x before 4.3.77 allows remote authenticated users to cause a denial of service (infinite loop or crash) by pointing the key file at the log file.
Weakness
The product contains an iteration or loop with an exit condition that cannot be reached, i.e., an infinite loop.
