CVE-2016-7427 1 Ntp 1 Ntp 2019-01-24 3.3 LOW 4.3 MEDIUM
The broadcast mode replay prevention functionality in ntpd in NTP before 4.2.8p9 allows remote attackers to cause a denial of service (reject broadcast mode packets) via a crafted broadcast mode packet.
CVE-2016-7428 1 Ntp 1 Ntp 2019-01-24 3.3 LOW 4.3 MEDIUM
ntpd in NTP before 4.2.8p9 allows remote attackers to cause a denial of service (reject broadcast mode packets) via the poll interval in a broadcast packet.
CVE-2016-9310 1 Ntp 1 Ntp 2019-01-24 6.4 MEDIUM 6.5 MEDIUM
The control mode (mode 6) functionality in ntpd in NTP before 4.2.8p9 allows remote attackers to set or unset traps via a crafted control mode packet.
CVE-2016-9311 1 Ntp 1 Ntp 2019-01-24 7.1 HIGH 5.9 MEDIUM
ntpd in NTP before 4.2.8p9, when the trap service is enabled, allows remote attackers to cause a denial of service (NULL pointer dereference and crash) via a crafted packet.
CVE-2017-6462 1 Ntp 1 Ntp 2019-01-24 4.6 MEDIUM 7.8 HIGH
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 1 Ntp 1 Ntp 2019-01-24 4.0 MEDIUM 6.5 MEDIUM
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-2015-5300 7 Canonical, Debian, Fedoraproject and 4 more 20 Ubuntu Linux, Debian Linux, Fedora and 17 more 2018-10-30 5.0 MEDIUM 7.5 HIGH
The panic_gate check in NTP before 4.2.8p5 is only re-enabled after the first change to the system clock that was greater than 128 milliseconds by default, which allows remote attackers to set NTP to an arbitrary time when started with the -g option, or to alter the time by up to 900 seconds otherwise by responding to an unspecified number of requests from trusted sources, and leveraging a resulting denial of service (abort and restart).
CVE-2013-5211 2 Ntp, Opensuse 2 Ntp, Opensuse 2018-10-30 5.0 MEDIUM N/A
The monlist feature in ntp_request.c in ntpd in NTP before 4.2.7p26 allows remote attackers to cause a denial of service (traffic amplification) via forged (1) REQ_MON_GETLIST or (2) REQ_MON_GETLIST_1 requests, as exploited in the wild in December 2013.
CVE-2015-7976 4 Novell, Ntp, Opensuse and 1 more 10 Suse Openstack Cloud, Ntp, Leap and 7 more 2018-10-30 4.0 MEDIUM 4.3 MEDIUM
The ntpq saveconfig command in NTP 4.1.2, 4.2.x before 4.2.8p6, 4.3, 4.3.25, 4.3.70, and 4.3.77 does not properly filter special characters, which allows attackers to cause unspecified impact via a crafted filename.
CVE-2009-0159 1 Ntp 1 Ntp 2018-10-11 6.8 MEDIUM N/A
Stack-based buffer overflow in the cookedprint function in ntpq/ntpq.c in ntpq in NTP before 4.2.4p7-RC2 allows remote NTP servers to execute arbitrary code via a crafted response.
CVE-2009-0021 1 Ntp 1 Ntp 2018-10-11 5.0 MEDIUM N/A
NTP 4.2.4 before 4.2.4p5 and 4.2.5 before 4.2.5p150 does not properly check the return value from the OpenSSL EVP_VerifyFinal function, which allows remote attackers to bypass validation of the certificate chain via a malformed SSL/TLS signature for DSA and ECDSA keys, a similar vulnerability to CVE-2008-5077.
CVE-2009-1252 1 Ntp 1 Ntp 2018-10-10 6.8 MEDIUM N/A
Stack-based buffer overflow in the crypto_recv function in ntp_crypto.c in ntpd in NTP before 4.2.4p7 and 4.2.5 before 4.2.5p74, when OpenSSL and autokey are enabled, allows remote attackers to execute arbitrary code via a crafted packet containing an extension field.
CVE-2015-5146 3 Debian, Fedoraproject, Ntp 3 Debian Linux, Fedora, Ntp 2018-08-01 3.5 LOW 5.3 MEDIUM
ntpd in ntp before 4.2.8p3 with remote configuration enabled allows remote authenticated users with knowledge of the configuration password and access to a computer entrusted to perform remote configuration to cause a denial of service (service crash) via a NULL byte in a crafted configuration directive packet.
CVE-2015-7978 1 Ntp 1 Ntp 2018-05-17 5.0 MEDIUM 7.5 HIGH
NTP before 4.2.8p6 and 4.3.0 before 4.3.90 allows a remote attackers to cause a denial of service (stack exhaustion) via an ntpdc relist command, which triggers recursive traversal of the restriction list.
CVE-2017-6464 1 Ntp 1 Ntp 2018-04-11 4.0 MEDIUM 6.5 MEDIUM
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-2016-1549 1 Ntp 1 Ntp 2018-03-27 4.0 MEDIUM 6.5 MEDIUM
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-2016-7429 1 Ntp 1 Ntp 2018-01-04 4.3 MEDIUM 3.7 LOW
NTP before 4.2.8p9 changes the peer structure to the interface it receives the response from a source, which allows remote attackers to cause a denial of service (prevent communication with a source) by sending a response for a source to an interface the source does not use.
CVE-2015-1799 1 Ntp 1 Ntp 2018-01-04 4.3 MEDIUM N/A
The symmetric-key feature in the receive function in ntp_proto.c in ntpd in NTP 3.x and 4.x before 4.2.8p2 performs state-variable updates upon receiving certain invalid packets, which makes it easier for man-in-the-middle attackers to cause a denial of service (synchronization loss) by spoofing the source IP address of a peer.
CVE-2015-8158 1 Ntp 1 Ntp 2018-01-04 4.3 MEDIUM 5.9 MEDIUM
The getresponse function in ntpq in NTP versions before 4.2.8p9 and 4.3.x before 4.3.90 allows remote attackers to cause a denial of service (infinite loop) via crafted packets with incorrect values.
CVE-2015-8139 1 Ntp 1 Ntp 2017-11-20 5.0 MEDIUM 5.3 MEDIUM
ntpq in NTP before 4.2.8p7 allows remote attackers to obtain origin timestamps and then impersonate peers via unspecified vectors.
