ntp: ntpd crash when processing config commands with statistics type
ntp_openssl.m4 in ntpd in NTP before 4.2.7p112 allows remote attackers to cause a denial of service (segmentation fault) via a crafted statistics or filegen configuration command that is not enabled during compilation.
It was found that ntpd would exit with a segmentation fault when a statistics type that was not enabled during compilation (e.g. timingstats) was referenced by the statistics or filegen configuration command.

CVE-2015-5195 ntp: ntpd crash when processing config commands with statistics type
It was found that ntpd exits with a segmentation fault when a statistics type that was not enabled during compilation (e.g. timingstats) is referenced by the statistics or filegen configuration command, for example:
ntpq -c ':config statistics timingstats'
ntpq -c ':config filegen timingstats'
