CVE-2017-6462

A vulnerability was found in NTP, in the parsing of packets from the /dev/datum device. A malicious device could send crafted messages, causing ntpd to crash. Mitigation Properly monitor your ntpd instances, and auto-restart ntpd without -g if it stops running...

CVE-2017-6463

A vulnerability was discovered in the NTP server's parsing of configuration directives. A remote, authenticated attacker could cause ntpd to crash by sending a crafted message. Mitigation Properly monitor your ntpd instances, and auto-restart ntpd without -g if it stops running...

CVE-2017-6460

A vulnerability was found in NTP, in the ntpq program. A malicious server could send a specially crafted response which would cause a stack buffer overflow, leading to a crash or potential code execution...

CVE-2017-6458

A vulnerability was found in NTP, in the building of response packets with custom fields. If custom fields were configured in ntp.conf with particularly long names, inclusion of these fields in the response packet could cause a buffer overflow, leading to a crash. Mitigation Implement BCP-38. If...
