CVE-2015-7691 | 5 Debian, Netapp, Ntp and 2 more | 13 Debian Linux, Clustered Data Ontap, Data Ontap and 10 more | 2024-02-28 | 5.0 MEDIUM | 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-2015-7975 | 1 Ntp | 1 Ntp | 2024-02-28 | 2.1 LOW | 6.2 MEDIUM |
The nextvar function in NTP before 4.2.8p6 and 4.3.x before 4.3.90 does not properly validate the length of its input, which allows an attacker to cause a denial of service (application crash). | |||||
CVE-2016-7429 | 1 Ntp | 1 Ntp | 2024-02-28 | 4.3 MEDIUM | 3.7 LOW |
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-2016-2519 | 1 Ntp | 1 Ntp | 2024-02-28 | 4.9 MEDIUM | 5.9 MEDIUM |
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-2016-1549 | 1 Ntp | 1 Ntp | 2024-02-28 | 4.0 MEDIUM | 6.5 MEDIUM |
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 | 1 Ntp | 1 Ntp | 2024-02-28 | 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-2017-6451 | 1 Ntp | 1 Ntp | 2024-02-28 | 4.6 MEDIUM | 7.8 HIGH |
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-2015-7979 | 1 Ntp | 1 Ntp | 2024-02-28 | 5.0 MEDIUM | 7.5 HIGH |
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-2016-1551 | 2 Ntp, Ntpsec | 2 Ntp, Ntpsec | 2024-02-28 | 2.6 LOW | 3.7 LOW |
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-2015-7977 | 8 Canonical, Debian, Fedoraproject and 5 more | 12 Ubuntu Linux, Debian Linux, Fedora and 9 more | 2024-02-28 | 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-2015-7976 | 4 Novell, Ntp, Opensuse and 1 more | 10 Suse Openstack Cloud, Ntp, Leap and 7 more | 2024-02-28 | 4.0 MEDIUM | 4.3 MEDIUM |
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-2017-6459 | 1 Ntp | 1 Ntp | 2024-02-28 | 2.1 LOW | 5.5 MEDIUM |
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-2016-7428 | 1 Ntp | 1 Ntp | 2024-02-28 | 3.3 LOW | 4.3 MEDIUM |
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 | 2024-02-28 | 5.0 MEDIUM | 5.3 MEDIUM |
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-2016-7427 | 1 Ntp | 1 Ntp | 2024-02-28 | 3.3 LOW | 4.3 MEDIUM |
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-2016-1550 | 1 Ntp | 1 Ntp | 2024-02-28 | 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-2017-6464 | 1 Ntp | 1 Ntp | 2024-02-28 | 4.0 MEDIUM | 6.5 MEDIUM |
NTP before 4.2.8p10 and 4.3.x before 4.3.94 allows remote attackers to cause a denial of service (ntpd crash) via a malformed mode configuration directive. | |||||
CVE-2017-6455 | 1 Ntp | 1 Ntp | 2024-02-28 | 4.4 MEDIUM | 7.0 HIGH |
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-2016-7433 | 1 Ntp | 1 Ntp | 2024-02-28 | 5.0 MEDIUM | 5.3 MEDIUM |
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." | |||||
