CVE-2015-7855 4 Debian, Netapp, Ntp and 1 more 11 Debian Linux, Clustered Data Ontap, Data Ontap and 8 more 2025-04-20 6.5 Medium
The decodenetnum 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 (assertion failure) via a 6 or mode 7 packet containing a long data value.
CVE-2016-2517 1 Ntp 1 Ntp 2025-04-20 N/A
NTP before 4.2.8p7 and 4.3.x before 4.3.92 allows remote attackers to cause a denial of service (prevent subsequent authentication) by leveraging knowledge of the controlkey or requestkey and sending a crafted packet to ntpd, which changes the value of trustedkey, controlkey, or requestkey. NOTE: this vulnerability exists because of a CVE-2016-2516 regression.
CVE-2016-2519 1 Ntp 1 Ntp 2025-04-20 N/A
ntpd in NTP before 4.2.8p7 and 4.3.x before 4.3.92 allows remote attackers to cause a denial of service (ntpd abort) by a large request data value, which triggers the ctl_getitem function to return a NULL value.
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-2016-7431 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-2016-9310 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-2015-7973 5 Canonical, Freebsd, Netapp and 2 more 9 Ubuntu Linux, Freebsd, Clustered Data Ontap and 6 more 2025-04-20 6.5 Medium
NTP before 4.2.8p6 and 4.3.x before 4.3.90, when configured in broadcast mode, allows man-in-the-middle 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-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-2015-8158 2 Ntp, Redhat 2 Ntp, Enterprise Linux 2025-04-20 N/A
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-2017-6458 4 Apple, Hpe, Ntp and 1 more 5 Mac Os X, Hpux-ntp, Ntp and 2 more 2025-04-20 8.8 High
Multiple buffer overflows in the ctl_put* functions in NTP before 4.2.8p10 and 4.3.x before 4.3.94 allow remote authenticated users to have unspecified impact via a long variable.
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-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-2017-6451 1 Ntp 1 Ntp 2025-04-20 N/A
The mx4200_send function in the legacy MX4200 refclock in NTP before 4.2.8p10 and 4.3.x before 4.3.94 does not properly handle the return value of the snprintf function, which allows local users to execute arbitrary code via unspecified vectors, which trigger an out-of-bounds memory write.
CVE-2016-7427 1 Ntp 1 Ntp 2025-04-20 N/A
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-2015-7701 5 Debian, Netapp, Ntp and 2 more 14 Debian Linux, Clustered Data Ontap, Data Ontap and 11 more 2025-04-20 7.5 High
Memory leak in the CRYPTO_ASSOC 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 (memory consumption).
CVE-2016-7429 2 Ntp, Redhat 2 Ntp, Enterprise Linux 2025-04-20 N/A
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-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-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-2016-7426 4 Canonical, Hpe, Ntp and 1 more 10 Ubuntu Linux, Hpux-ntp, Ntp and 7 more 2025-04-20 7.5 High
NTP before 4.2.8p9 rate limits responses received from the configured sources when rate limiting for all associations is enabled, which allows remote attackers to cause a denial of service (prevent responses from the sources) by sending responses with a spoofed source address.
