| 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-2016-9312 | 2 Microsoft, Ntp | 2 Windows, Ntp | 2025-04-20 | N/A |
| ntpd in NTP before 4.2.8p9, when running on Windows, allows remote attackers to cause a denial of service via a large UDP packet. | ||||
| CVE-2016-9310 | 2 Ntp, Redhat | 2 Ntp, Enterprise Linux | 2025-04-20 | N/A |
| 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-2015-3405 | 7 Debian, Fedoraproject, Ntp and 4 more | 14 Debian Linux, Fedora, Ntp and 11 more | 2025-04-20 | N/A |
| 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-2015-5146 | 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-2015-5194 | 6 Canonical, Debian, Fedoraproject and 3 more | 14 Ubuntu Linux, Debian Linux, Fedora and 11 more | 2025-04-20 | N/A |
| The log_config_command function in ntp_parser.y in ntpd in NTP before 4.2.7p42 allows remote attackers to cause a denial of service (ntpd crash) via crafted logconfig commands. | ||||
| CVE-2014-9296 | 2 Ntp, Redhat | 3 Ntp, Enterprise Linux, Rhel Eus | 2025-04-12 | 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. | ||||
| CVE-2014-9295 | 2 Ntp, Redhat | 3 Ntp, Enterprise Linux, Rhel Eus | 2025-04-12 | 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-2014-9750 | 4 Debian, Ntp, Oracle and 1 more | 7 Debian Linux, Ntp, Linux and 4 more | 2025-04-12 | N/A |
| ntp_crypto.c in ntpd in NTP 4.x before 4.2.8p1, when Autokey Authentication is enabled, allows remote attackers to obtain sensitive information from process memory or cause a denial of service (daemon crash) via a packet containing an extension field with an invalid value for the length of its value field. | ||||
| CVE-2015-1798 | 2 Ntp, Redhat | 2 Ntp, Enterprise Linux | 2025-04-12 | 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-2015-1799 | 2 Ntp, Redhat | 2 Ntp, Enterprise Linux | 2025-04-12 | 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-2016-4956 | 6 Novell, Ntp, Opensuse and 3 more | 11 Suse Manager, Ntp, Leap and 8 more | 2025-04-12 | 5.3 Medium |
| 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-2015-7974 | 5 Debian, Netapp, Ntp and 2 more | 9 Debian Linux, Clustered Data Ontap, Oncommand Balance and 6 more | 2025-04-12 | 7.7 High |
| NTP 4.x before 4.2.8p6 and 4.3.x before 4.3.90 do not verify peer associations of symmetric keys when authenticating packets, which might allow remote attackers to conduct impersonation attacks via an arbitrary trusted key, aka a "skeleton key." | ||||
| CVE-2014-9293 | 2 Ntp, Redhat | 3 Ntp, Enterprise Linux, Rhel Eus | 2025-04-12 | 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-2014-9294 | 2 Ntp, Redhat | 3 Ntp, Enterprise Linux, Rhel Eus | 2025-04-12 | 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-2016-4955 | 6 Novell, Ntp, Opensuse and 3 more | 11 Suse Manager, Ntp, Leap and 8 more | 2025-04-12 | 5.9 Medium |
| 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-2016-4954 | 5 Ntp, Opensuse, Oracle and 2 more | 15 Ntp, Leap, Opensuse and 12 more | 2025-04-12 | 7.5 High |
| 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-2016-4953 | 5 Ntp, Opensuse, Oracle and 2 more | 15 Ntp, Leap, Opensuse and 12 more | 2025-04-12 | 7.5 High |
| ntpd in NTP 4.x before 4.2.8p8 allows remote attackers to cause a denial of service (ephemeral-association demobilization) by sending a spoofed crypto-NAK packet with incorrect authentication data at a certain time. | ||||
| CVE-2014-9751 | 6 Apple, Debian, Linux and 3 more | 9 Macos, Debian Linux, Linux Kernel and 6 more | 2025-04-12 | N/A |
| The read_network_packet function in ntp_io.c in ntpd in NTP 4.x before 4.2.8p1 on Linux and OS X does not properly determine whether a source IP address is an IPv6 loopback address, which makes it easier for remote attackers to spoof restricted packets, and read or write to the runtime state, by leveraging the ability to reach the ntpd machine's network interface with a packet from the ::1 address. | ||||
| CVE-2016-4957 | 5 Novell, Ntp, Opensuse and 2 more | 9 Suse Manager, Ntp, Leap and 6 more | 2025-04-12 | 7.5 High |
| ntpd in NTP before 4.2.8p8 allows remote attackers to cause a denial of service (daemon crash) via a crypto-NAK packet. NOTE: this vulnerability exists because of an incorrect fix for CVE-2016-1547. | ||||
