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-2017-6460 1 Ntp 1 Ntp 2025-04-20 N/A
Stack-based buffer overflow in the reslist function in ntpq in NTP before 4.2.8p10 and 4.3.x before 4.3.94 allows remote servers have unspecified impact via a long flagstr variable in a restriction list response.
CVE-2016-7434 2 Hpe, Ntp 2 Hpux-ntp, Ntp 2025-04-20 7.5 High
The read_mru_list function in NTP before 4.2.8p9 allows remote attackers to cause a denial of service (crash) via a crafted mrulist query.
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-2016-1550 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-2015-3405 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-2015-7691 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.
CVE-2015-7849 2 Netapp, Ntp 6 Clustered Data Ontap, Data Ontap, Oncommand Balance and 3 more 2025-04-20 8.8 High
Use-after-free vulnerability in ntpd in NTP 4.2.x before 4.2.8p4, and 4.3.x before 4.3.77 allows remote authenticated users to possibly execute arbitrary code or cause a denial of service (crash) via crafted packets.
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-2016-1551 2 Ntp, Ntpsec 2 Ntp, Ntpsec 2025-04-20 N/A
ntpd in NTP 4.2.8p3 and NTPsec a5fb34b9cc89b92a8fef2f459004865c93bb7f92 relies on the underlying operating system to protect it from requests that impersonate reference clocks. Because reference clocks are treated like other peers and stored in the same structure, any packet with a source ip address of a reference clock (127.127.1.1 for example) that reaches the receive() function will match that reference clock's peer record and will be treated as a trusted peer. Any system that lacks the typical martian packet filtering which would block these packets is in danger of having its time controlled by an attacker.
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-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-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-2017-6455 1 Ntp 1 Ntp 2025-04-20 N/A
NTP before 4.2.8p10 and 4.3.x before 4.3.94, when using PPSAPI, allows local users to gain privileges via a DLL in the PPSAPI_DLLS environment variable.
CVE-2017-6459 1 Ntp 1 Ntp 2025-04-20 N/A
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 vectors related to an argument with multiple null bytes.
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-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-2015-7871 3 Debian, Netapp, Ntp 7 Debian Linux, Clustered Data Ontap, Data Ontap and 4 more 2025-04-20 9.8 Critical
Crypto-NAK packets in ntpd in NTP 4.2.x before 4.2.8p4, and 4.3.x before 4.3.77 allows remote attackers to bypass authentication.
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.
