CVE-2015-5194
The log_config_command function in ntp_parser.y in ntpd in NTP before 4.2.7p42 allows remote attackers to cause a denial of service (ntpd crash) via crafted logconfig commands.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (6.48%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
