ntpq in NTP 4.2.x before 4.2.8p4, and 4.3.x before 4.3.77 allows remote attackers to cause a denial of service (crash) via crafted mode 6 response packets. (CVE-2015-7852)
Impact
While the scope of the impact is limited, an attacker may be able to craft response packets that cause ntpqto exit. There is no data plane exposure for the BIG-IP system, and this issue can only be exposed when an instance of ntpq is running in interactive mode.
