CVE-2015-5195
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.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (8.75%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.

EPSS moved from 8.8% on 7 October 2026 to 8.8% on 26 October 2026. The dashed line is the ten per cent mark our analysts treat as “patch before the next change window”.
