Red Hat Product Security has rated this update as having a security
impact of Moderate. A Common Vulnerability Scoring System (CVSS) base
score, which gives a detailed severity rating, is available for each
vulnerability from the CVE link(s) in the References section.

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)

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

"Ephemeral association time spoofing additional protection

ntpd in ntp 4.2.x before 4.2.8p7 and 4.3.x before 4.3.92 allows
authenticated users that know the private symmetric key to create
arbitrarily-many ephemeral associations in order to win the clock
selection of ntpd and modify a victim's clock via a Sybil attack. This
issue exists because of an incomplete fix for CVE-2016-1549
.(CVE-2018-7170)

Interleaved symmetric mode cannot recover from bad state

ntpd in ntp 4.2.8p4 before 4.2.8p11 drops bad packets before updating
the 'received' timestamp, which allows remote attackers to cause a
denial of service (disruption) by sending a packet with a zero-origin
timestamp causing the association to reset and setting the contents of
the packet as the most recent timestamp. This issue is a result of an
incomplete fix for CVE-2015-7704 .(CVE-2018-7184)

Ephemeral association time spoofing

A malicious authenticated peer can create arbitrarily-many ephemeral
associations in order to win the clock selection algorithm in ntpd in
NTP 4.2.8p4 and earlier and NTPsec
3e160db8dc248a0bcb053b56a80167dc742d2b74 and
a5fb34b9cc89b92a8fef2f459004865c93bb7f92 and modify a victim's
clock.(CVE-2016-1549)

Buffer read overrun leads information leak in ctl_getitem()

The ctl_getitem method in ntpd in ntp-4.2.8p6 before 4.2.8p11 allows
remote attackers to cause a denial of service (out-of-bounds read) via
a crafted mode 6 packet with a ntpd instance from 4.2.8p6 through
4.2.8p10. (CVE-2018-7182)

Unauthenticated packet can reset authenticated interleaved association

The protocol engine in ntp 4.2.6 before 4.2.8p11 allows a remote
attackers to cause a denial of service (disruption) by continually
sending a packet with a zero-origin timestamp and source IP address of
the 'other side' of an interleaved association causing the victim ntpd
to reset its association.(CVE-2018-7185)

decodearr() can write beyond its buffer limit

Buffer overflow in the decodearr function in ntpq in ntp 4.2.8p6
through 4.2.8p10 allows remote attackers to execute arbitrary code by
leveraging an ntpq query and sending a response with a crafted
array.(CVE-2018-7183)"

    is enabled, allows remote attackers to cause a denial
    of service (ntpd abort) by using the same IP address
    multiple times in an unconfig directive.(CVE-2016-2516)

  - The process_packet function in ntp_proto.c in ntpd in
    NTP 4.x before 4.2.8p8 allows remote attackers to cause
    a denial of service (peer-variable modification) by
    sending spoofed packets from many source IP addresses
    in a certain scenario, as demonstrated by triggering an
    incorrect leap indication.(CVE-2016-4954)

  - ntpd in NTP 4.x before 4.2.8p8, when autokey is
    enabled, allows remote attackers to cause a denial of
    service (peer-variable clearing and association outage)
    by sending (1) a spoofed crypto-NAK packet or (2) a
    packet with an incorrect MAC value at a certain
    time.(CVE-2016-4955)

  - ntpd in NTP 4.x before 4.2.8p8 allows remote attackers
    to cause a denial of service (interleaved-mode
    transition and time change) via a spoofed broadcast
    packet. NOTE: this vulnerability exists because of an
    incomplete fix for CVE-2016-1548.(CVE-2016-4956)

  - 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-2017-6462)

  - 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-2017-6463)

  - 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.(CVE-2017-6464)
