CVE-2017-6462 [HIGH] CWE-20 ntp: Buffer Overflow in DPTS Clock
ntp: Buffer Overflow in DPTS Clock
Buffer overflow in the legacy Datum Programmable Time Server (DPTS) refclock driver in NTP before 4.2.8p10 and 4.3.x before 4.3.94 allows local users to have unspecified impact via a crafted /dev/datum device.
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-2017-6462 [HIGH] CVE-2017-6462 ntp: Buffer Overflow in DPTS Clock
CVE-2017-6462 ntp: Buffer Overflow in DPTS Clock
There is a potential for a buffer overflow in the legacy Datum Programmable Time Server refclock driver. Here the packets are processed from the /dev/datum device and handled in datum_pts_receive(). Since an attacker would be required to somehow control a malicious /dev/datum device, this does not appear to be a practical attack and renders this issue "Low" in terms of severity.
Affects: All versions of NTP, up to but not including ntp-4.2.8p10, and ntp-4.3.0 up to, but not including ntp-4.3.94.
Mitigation:
Properly monitor your ntpd instances, and auto-restart ntpd (without -g) if it stops running.
