CVE-2016-1550 2 Ntp, Redhat 3 Ntp, Enterprise Linux, Rhel Eus 2025-04-20 N/A
An exploitable vulnerability exists in the message authentication functionality of libntp in ntp 4.2.8p4 and NTPSec a5fb34b9cc89b92a8fef2f459004865c93bb7f92. An attacker can send a series of crafted messages to attempt to recover the message digest key.
CVE-2015-7976 4 Novell, Ntp, Opensuse and 1 more 10 Suse Openstack Cloud, Ntp, Leap and 7 more 2025-04-20 N/A
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-2015-7977 9 Canonical, Debian, Fedoraproject and 6 more 13 Ubuntu Linux, Debian Linux, Fedora and 10 more 2025-04-20 5.9 Medium
ntpd in NTP before 4.2.8p6 and 4.3.x before 4.3.90 allows remote attackers to cause a denial of service (NULL pointer dereference) via a ntpdc reslist command.
CVE-2015-7978 2 Ntp, Redhat 2 Ntp, Enterprise Linux 2025-04-20 N/A
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-2015-7979 2 Ntp, Redhat 3 Ntp, Enterprise Linux, Rhel Eus 2025-04-20 N/A
NTP before 4.2.8p6 and 4.3.x before 4.3.90 allows remote attackers to cause a denial of service (client-server association tear down) by sending broadcast packets with invalid authentication to a broadcast client.
CVE-2015-8139 1 Ntp 1 Ntp 2025-04-20 N/A
ntpq in NTP before 4.2.8p7 allows remote attackers to obtain origin timestamps and then impersonate peers via unspecified vectors.
CVE-2015-8140 1 Ntp 1 Ntp 2025-04-20 N/A
The ntpq protocol in NTP before 4.2.8p7 allows remote attackers to conduct replay attacks by sniffing the network.
CVE-2016-1547 2 Ntp, Redhat 3 Ntp, Enterprise Linux, Rhel Eus 2025-04-20 N/A
An off-path attacker can cause a preemptible client association to be demobilized in NTP 4.2.8p4 and earlier and NTPSec a5fb34b9cc89b92a8fef2f459004865c93bb7f92 by sending a crypto NAK packet to a victim client with a spoofed source address of an existing associated peer. This is true even if authentication is enabled.
CVE-2016-1549 1 Ntp 1 Ntp 2025-04-20 N/A
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-2016-1548 2 Ntp, Redhat 3 Ntp, Enterprise Linux, Rhel Eus 2025-04-20 N/A
An attacker can spoof a packet from a legitimate ntpd server with an origin timestamp that matches the peer->dst timestamp recorded for that server. After making this switch, the client in NTP 4.2.8p4 and earlier and NTPSec aa48d001683e5b791a743ec9c575aaf7d867a2b0c will reject all future legitimate server responses. It is possible to force the victim client to move time after the mode has been changed. ntpq gives no indication that the mode has been switched.
CVE-2015-7692 5 Debian, Netapp, Ntp and 2 more 14 Debian Linux, Clustered Data Ontap, Data Ontap and 11 more 2025-04-20 7.5 High
The crypto_xmit function in ntpd in NTP 4.2.x before 4.2.8p4, and 4.3.x before 4.3.77 allows remote attackers to cause a denial of service (crash). NOTE: This vulnerability exists due to an incomplete fix for CVE-2014-9750.
CVE-2017-6462 2 Ntp, Redhat 2 Ntp, Enterprise Linux 2025-04-20 N/A
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-2015-7702 5 Debian, Netapp, Ntp and 2 more 14 Debian Linux, Clustered Data Ontap, Data Ontap and 11 more 2025-04-20 6.5 Medium
The crypto_xmit function in ntpd in NTP 4.2.x before 4.2.8p4, and 4.3.x before 4.3.77 allows remote attackers to cause a denial of service (crash). NOTE: This vulnerability exists due to an incomplete fix for CVE-2014-9750.
CVE-2017-6452 1 Ntp 1 Ntp 2025-04-20 N/A
Stack-based buffer overflow in the Windows installer for NTP before 4.2.8p10 and 4.3.x before 4.3.94 allows local users to have unspecified impact via an application path on the command line.
CVE-2015-5146 3 Debian, Fedoraproject, Ntp 3 Debian Linux, Fedora, Ntp 2025-04-20 N/A
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-2016-7428 1 Ntp 1 Ntp 2025-04-20 N/A
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-2016-7431 1 Ntp 1 Ntp 2025-04-20 N/A
NTP before 4.2.8p9 allows remote attackers to bypass the origin timestamp protection mechanism via an origin timestamp of zero. NOTE: this vulnerability exists because of a CVE-2015-8138 regression.
CVE-2016-7433 2 Ntp, Redhat 2 Ntp, Enterprise Linux 2025-04-20 N/A
NTP before 4.2.8p9 does not properly perform the initial sync calculations, which allows remote attackers to unspecified impact via unknown vectors, related to a "root distance that did not include the peer dispersion."
CVE-2015-7853 2 Netapp, Ntp 6 Clustered Data Ontap, Data Ontap, Oncommand Balance and 3 more 2025-04-20 9.8 Critical
The datalen parameter in the refclock driver in NTP 4.2.x before 4.2.8p4, and 4.3.x before 4.3.77 allows remote attackers to execute arbitrary code or cause a denial of service (crash) via a negative input value.
CVE-2015-7691 5 Debian, Netapp, Ntp and 2 more 14 Debian Linux, Clustered Data Ontap, Data Ontap and 11 more 2025-04-20 7.5 High
The crypto_xmit function in ntpd in NTP 4.2.x before 4.2.8p4, and 4.3.x before 4.3.77 allows remote attackers to cause a denial of service (crash) via crafted packets containing particular autokey operations. NOTE: This vulnerability exists due to an incomplete fix for CVE-2014-9750.
