| CVE-2016-4953 | 5 Ntp, Opensuse, Oracle and 2 more | 15 Ntp, Leap, Opensuse and 12 more | 2024-08-06 | 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-2016-4955 | 6 Novell, Ntp, Opensuse and 3 more | 11 Suse Manager, Ntp, Leap and 8 more | 2024-08-06 | 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 | 2024-08-06 | 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-2016-2519 | 1 Ntp | 1 Ntp | 2024-08-05 | 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-2016-2518 | 7 Debian, Freebsd, Netapp and 4 more | 20 Debian Linux, Freebsd, Clustered Data Ontap and 17 more | 2024-08-05 | 5.3 Medium |
| The MATCH_ASSOC function in NTP before version 4.2.8p9 and 4.3.x before 4.3.92 allows remote attackers to cause an out-of-bounds reference via an addpeer request with a large hmode value. | ||||
| CVE-2016-2517 | 1 Ntp | 1 Ntp | 2024-08-05 | 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-2016-2516 | 1 Ntp | 1 Ntp | 2024-08-05 | N/A |
| NTP before 4.2.8p7 and 4.3.x before 4.3.92, when mode7 is enabled, allows remote attackers to cause a denial of service (ntpd abort) by using the same IP address multiple times in an unconfig directive. | ||||
| CVE-2016-1551 | 2 Ntp, Ntpsec | 2 Ntp, Ntpsec | 2024-08-05 | 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-2016-1549 | 1 Ntp | 1 Ntp | 2024-08-05 | N/A |
| 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-2016-1547 | 2 Ntp, Redhat | 3 Ntp, Enterprise Linux, Rhel Eus | 2024-08-05 | 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-2016-1550 | 2 Ntp, Redhat | 3 Ntp, Enterprise Linux, Rhel Eus | 2024-08-05 | 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-2016-1548 | 2 Ntp, Redhat | 3 Ntp, Enterprise Linux, Rhel Eus | 2024-08-05 | N/A |
| 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-2017-6462 | 2 Ntp, Redhat | 2 Ntp, Enterprise Linux | 2024-08-05 | N/A |
| Buffer overflow in the legacy Datum Programmable Time Server (DPTS) refclock driver in NTP before 4.2.8p10 and 4.3.x before 4.3.94 allows local users to have unspecified impact via a crafted /dev/datum device. | ||||
| CVE-2017-6464 | 2 Ntp, Redhat | 2 Ntp, Enterprise Linux | 2024-08-05 | N/A |
| 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-2017-6451 | 1 Ntp | 1 Ntp | 2024-08-05 | 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-2017-6455 | 1 Ntp | 1 Ntp | 2024-08-05 | 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 | 2024-08-05 | 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-2017-6458 | 4 Apple, Hpe, Ntp and 1 more | 5 Mac Os X, Hpux-ntp, Ntp and 2 more | 2024-08-05 | 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-2017-6452 | 1 Ntp | 1 Ntp | 2024-08-05 | N/A |
| Stack-based buffer overflow in 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 an application path on the command line. | ||||
| CVE-2017-6460 | 1 Ntp | 1 Ntp | 2024-08-05 | 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. | ||||
