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. | |||||

An Information Disclosure vulnerability exists in NTP 4.2.7p25 private (mode 6/7) messages via a GET_RESTRICT control message, which could let a malicious user obtain sensitive information. | |||||
CVE-2013-5211 | 3 Ntp, Opensuse, Oracle | 3 Ntp, Opensuse, Linux | 2023-11-01 | 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-2015-5219 | 10 Canonical, Debian, Fedoraproject and 7 more | 20 Ubuntu Linux, Debian Linux, Fedora and 17 more | 2023-02-13 | 5.0 MEDIUM | 7.5 HIGH |
The ULOGTOD function in ntp.d in SNTP before 4.2.7p366 does not properly perform type conversions from a precision value to a double, which allows remote attackers to cause a denial of service (infinite loop) via a crafted NTP packet. | |||||
CVE-2015-5194 | 6 Canonical, Debian, Fedoraproject and 3 more | 13 Ubuntu Linux, Debian Linux, Fedora and 10 more | 2023-02-13 | 5.0 MEDIUM | 7.5 HIGH |

ntp-keygen in ntp 4.2.8px before 4.2.8p2-RC2 and 4.3.x before 4.3.12 does not generate MD5 keys with sufficient entropy on big endian machines when the lowest order byte of the temp variable is between 0x20 and 0x7f and not #, which might allow remote attackers to obtain the value of generated MD5 keys via a brute force attack with the 93 possible keys. | |||||
CVE-2015-1798 | 1 Ntp | 1 Ntp | 2023-02-12 | 1.8 LOW | N/A |
The symmetric-key feature in the receive function in ntp_proto.c in ntpd in NTP 4.x before 4.2.8p2 requires a correct MAC only if the MAC field has a nonzero length, which makes it easier for man-in-the-middle attackers to spoof packets by omitting the MAC. | |||||
CVE-2015-7977 | 8 Canonical, Debian, Fedoraproject and 5 more | 12 Ubuntu Linux, Debian Linux, Fedora and 9 more | 2022-02-01 | 4.3 MEDIUM | 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-2016-1548 | 1 Ntp | 1 Ntp | 2021-11-17 | 6.4 MEDIUM | 7.2 HIGH |
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-2016-1550 | 1 Ntp | 1 Ntp | 2021-11-17 | 5.0 MEDIUM | 5.3 MEDIUM |
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-2015-8138 | 1 Ntp | 1 Ntp | 2021-11-17 | 5.0 MEDIUM | 5.3 MEDIUM |
NTP before 4.2.8p6 and 4.3.x before 4.3.90 allows remote attackers to bypass the origin timestamp validation via a packet with an origin timestamp set to zero. | |||||
CVE-2014-9294 | 1 Ntp | 1 Ntp | 2021-11-17 | 7.5 HIGH | N/A |
util/ntp-keygen.c in ntp-keygen in NTP before 4.2.7p230 uses a weak RNG seed, which makes it easier for remote attackers to defeat cryptographic protection mechanisms via a brute-force attack. | |||||
CVE-2016-1547 | 1 Ntp | 1 Ntp | 2021-11-17 | 5.0 MEDIUM | 5.3 MEDIUM |
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-2015-7705 | 4 Citrix, Netapp, Ntp and 1 more | 10 Xenserver, Clustered Data Ontap, Data Ontap and 7 more | 2021-11-17 | 7.5 HIGH | 9.8 CRITICAL |
The rate limiting feature in NTP 4.x before 4.2.8p4 and 4.3.x before 4.3.77 allows remote attackers to have unspecified impact via a large number of crafted requests. | |||||
CVE-2014-9293 | 1 Ntp | 1 Ntp | 2021-11-17 | 7.5 HIGH | N/A |
The config_auth function in ntpd in NTP before 4.2.7p11, when an auth key is not configured, improperly generates a key, which makes it easier for remote attackers to defeat cryptographic protection mechanisms via a brute-force attack. | |||||
CVE-2015-7704 | 6 Citrix, Debian, Mcafee and 3 more | 14 Xenserver, Debian Linux, Enterprise Security Manager and 11 more | 2021-11-17 | 5.0 MEDIUM | 7.5 HIGH |
The ntpd client in NTP 4.x before 4.2.8p4 and 4.3.x before 4.3.77 allows remote attackers to cause a denial of service via a number of crafted "KOD" messages. | |||||
CVE-2014-9295 | 1 Ntp | 1 Ntp | 2021-11-17 | 7.5 HIGH | N/A |
Multiple stack-based buffer overflows in ntpd in NTP before 4.2.8 allow remote attackers to execute arbitrary code via a crafted packet, related to (1) the crypto_recv function when the Autokey Authentication feature is used, (2) the ctl_putdata function, and (3) the configure function. | |||||
CVE-2014-9296 | 1 Ntp | 1 Ntp | 2021-11-17 | 5.0 MEDIUM | N/A |
The receive function in ntp_proto.c in ntpd in NTP before 4.2.8 continues to execute after detecting a certain authentication error, which might allow remote attackers to trigger an unintended association change via crafted packets. |
