NVD Description

Note: Versions mentioned in the description apply only to the upstream sntp package and not the sntp package as distributed by Oracle. See How to fix? for Oracle:7 relevant fixed versions and status.

ntpd in NTP before 4.2.8p9, when the trap service is enabled, allows remote attackers to cause a denial of service (NULL pointer dereference and crash) via a crafted packet.
