ntp-4.2.6p5-12.1.0.1.AXS4

The Network Time Protocol (NTP) is used to synchronize a computer's time with another referenced time source. These packages include the ntpd service which continuously adjusts system time and utilities used to query and configure the ntpd service.

Security Fix(es):

* Two vulnerabilities were discovered in the NTP server's parsing of configuration directives. A remote, authenticated attacker could cause ntpd to crash by sending a crafted message. (CVE-2017-6463, CVE-2017-6464)

* 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. (CVE-2017-6462)

Asianux would like to thank the NTP project for reporting these issues. Upstream acknowledges Cure53 as the original reporter of these issues.

CVE-2017-6462
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.
CVE-2017-6463
NTP before 4.2.8p10 and 4.3.x before 4.3.94 allows remote
authenticated users to cause a denial of service (daemon crash) via an
invalid setting in a :config directive, related to the unpeer option.
CVE-2017-6464
NTP before 4.2.8p10 and 4.3.x before 4.3.94 allows remote attackers to
cause a denial of service (ntpd crash) via a malformed mode
configuration directive.
