The ULOGTOD function in ntp.d in SNTP before 4.2.7p366 does not properly perform type conversions from a precision value to a double, which allows remote attackers to cause a denial of service (infinite loop) via a crafted NTP packet. | |||||
CVE-2015-5194 | 6 Canonical, Debian, Fedoraproject and 3 more | 13 Ubuntu Linux, Debian Linux, Fedora and 10 more | 2023-02-12 | 5.0 MEDIUM | 7.5 HIGH |
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-2015-5195 | 5 Canonical, Debian, Fedoraproject and 2 more | 8 Ubuntu Linux, Debian Linux, Fedora and 5 more | 2023-02-12 | 5.0 MEDIUM | 7.5 HIGH |
ntp_openssl.m4 in ntpd in NTP before 4.2.7p112 allows remote attackers to cause a denial of service (segmentation fault) via a crafted statistics or filegen configuration command that is not enabled during compilation. | |||||
CVE-2015-3405 | 7 Debian, Fedoraproject, Ntp and 4 more | 13 Debian Linux, Fedora, Ntp and 10 more | 2023-02-12 | 5.0 MEDIUM | 7.5 HIGH |
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-2015-1798 | 1 Ntp | 1 Ntp | 2023-02-12 | 1.8 LOW | 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-2020-15025 | 4 Netapp, Ntp, Opensuse and 1 more | 27 8300, 8300 Firmware, 8700 and 24 more | 2022-09-02 | 4.0 MEDIUM | 4.9 MEDIUM |
ntpd in ntp 4.2.8 before 4.2.8p15 and 4.3.x before 4.3.101 allows remote attackers to cause a denial of service (memory consumption) by sending packets, because memory is not freed in situations where a CMAC key is used and associated with a CMAC algorithm in the ntp.keys file. | |||||
CVE-2020-11868 | 5 Debian, Netapp, Ntp and 2 more | 24 Debian Linux, All Flash Fabric-attached Storage 8300, All Flash Fabric-attached Storage 8300 Firmware and 21 more | 2022-04-26 | 5.0 MEDIUM | 7.5 HIGH |
ntpd in ntp before 4.2.8p14 and 4.3.x before 4.3.100 allows an off-path attacker to block unauthenticated synchronization via a server mode packet with a spoofed source IP address, because transmissions are rescheduled even when a packet lacks a valid origin timestamp. | |||||
CVE-2016-9042 | 4 Freebsd, Hpe, Ntp and 1 more | 5 Freebsd, Hpux-ntp, Ntp and 2 more | 2022-04-19 | 4.3 MEDIUM | 5.9 MEDIUM |
An exploitable denial of service vulnerability exists in the origin timestamp check functionality of ntpd 4.2.8p9. A specially crafted unauthenticated network packet can be used to reset the expected origin timestamp for target peers. Legitimate replies from targeted peers will fail the origin timestamp check (TEST2) causing the reply to be dropped and creating a denial of service condition. | |||||
CVE-2020-13817 | 4 Fujitsu, Netapp, Ntp and 1 more | 40 M10-1, M10-1 Firmware, M10-4 and 37 more | 2022-03-29 | 5.8 MEDIUM | 7.4 HIGH |
ntpd in ntp before 4.2.8p14 and 4.3.x before 4.3.100 allows remote attackers to cause a denial of service (daemon exit or system time change) by predicting transmit timestamps for use in spoofed packets. The victim must be relying on unauthenticated IPv4 time sources. There must be an off-path attacker who can query time from the victim's ntpd instance. | |||||
CVE-2015-7977 | 8 Canonical, Debian, Fedoraproject and 5 more | 12 Ubuntu Linux, Debian Linux, Fedora and 9 more | 2022-02-01 | 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-2015-8138 | 1 Ntp | 1 Ntp | 2021-11-17 | 5.0 MEDIUM | 5.3 MEDIUM |
NTP before 4.2.8p6 and 4.3.x before 4.3.90 allows remote attackers to bypass the origin timestamp validation via a packet with an origin timestamp set to zero. | |||||
CVE-2015-7705 | 4 Citrix, Netapp, Ntp and 1 more | 10 Xenserver, Clustered Data Ontap, Data Ontap and 7 more | 2021-11-17 | 7.5 HIGH | 9.8 CRITICAL |
The rate limiting feature in NTP 4.x before 4.2.8p4 and 4.3.x before 4.3.77 allows remote attackers to have unspecified impact via a large number of crafted requests. | |||||
CVE-2016-1550 | 1 Ntp | 1 Ntp | 2021-11-17 | 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-2015-7704 | 6 Citrix, Debian, Mcafee and 3 more | 14 Xenserver, Debian Linux, Enterprise Security Manager and 11 more | 2021-11-17 | 5.0 MEDIUM | 7.5 HIGH |
The ntpd client in NTP 4.x before 4.2.8p4 and 4.3.x before 4.3.77 allows remote attackers to cause a denial of service via a number of crafted "KOD" messages. | |||||
CVE-2016-1547 | 1 Ntp | 1 Ntp | 2021-11-17 | 5.0 MEDIUM | 5.3 MEDIUM |
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-2016-1548 | 1 Ntp | 1 Ntp | 2021-11-17 | 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-2014-9294 | 1 Ntp | 1 Ntp | 2021-11-17 | 7.5 HIGH | 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-2014-9296 | 1 Ntp | 1 Ntp | 2021-11-17 | 5.0 MEDIUM | 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-2014-9293 | 1 Ntp | 1 Ntp | 2021-11-17 | 7.5 HIGH | 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-2014-9295 | 1 Ntp | 1 Ntp | 2021-11-17 | 7.5 HIGH | 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. |
