NVD Description

Note: Versions mentioned in the description apply only to the upstream ntp package and not the ntp package as distributed by Ubuntu. See How to fix? for Ubuntu:14.04 relevant fixed versions and status.

Buffer overflow in the decodearr function in ntpq in ntp 4.2.8p6 through 4.2.8p10 allows remote attackers to execute arbitrary code by leveraging an ntpq query and sending a response with a crafted array.
