CVE-2009-3563 1 Ntp 1 Ntp 2024-03-19 N/A
ntp_request.c in ntpd in NTP before 4.2.4p8, and 4.2.5, allows remote attackers to cause a denial of service (CPU and bandwidth consumption) by using MODE_PRIVATE to send a spoofed (1) request or (2) response packet that triggers a continuous exchange of MODE_PRIVATE error responses between two NTP daemons.
CVE-2023-26555 1 Ntp 1 Ntp 2023-11-07 6.4 Medium
praecis_parse in ntpd/refclock_palisade.c in NTP 4.2.8p15 has an out-of-bounds write. Any attack method would be complex, e.g., with a manipulated GPS receiver.
CVE-2020-15025 4 Netapp, Ntp, Opensuse and 1 more 27 8300, 8300 Firmware, 8700 and 24 more 2023-11-07 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-2019-8936 5 Fedoraproject, Hpe, Netapp and 2 more 6 Fedora, Hpux-ntp, Clustered Data Ontap and 3 more 2023-11-07 7.5 High
NTP through 4.2.8p12 has a NULL Pointer Dereference.
CVE-2019-11331 1 Ntp 1 Ntp 2023-11-07 N/A
Network Time Protocol (NTP), as specified in RFC 5905, uses port 123 even for modes where a fixed port number is not required, which makes it easier for remote attackers to conduct off-path attacks.
CVE-2017-6458 4 Apple, Hpe, Ntp and 1 more 5 Mac Os X, Hpux-ntp, Ntp and 2 more 2023-11-07 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-2016-9042 4 Freebsd, Hpe, Ntp and 1 more 5 Freebsd, Hpux-ntp, Ntp and 2 more 2023-11-07 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-2016-7433 1 Ntp 1 Ntp 2023-11-07 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-2016-4956 6 Novell, Ntp, Opensuse and 3 more 11 Suse Manager, Ntp, Leap and 8 more 2023-11-07 5.3 Medium
ntpd in NTP 4.x before 4.2.8p8 allows remote attackers to cause a denial of service (interleaved-mode transition and time change) via a spoofed broadcast packet. NOTE: this vulnerability exists because of an incomplete fix for CVE-2016-1548.
CVE-2016-4955 6 Novell, Ntp, Opensuse and 3 more 11 Suse Manager, Ntp, Leap and 8 more 2023-11-07 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 2023-11-07 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-2015-8139 1 Ntp 1 Ntp 2023-11-07 N/A
ntpq in NTP before 4.2.8p7 allows remote attackers to obtain origin timestamps and then impersonate peers via unspecified vectors.
CVE-2014-5209 2 F5, Ntp 25 Big-ip Access Policy Manager, Big-ip Advanced Firewall Manager, Big-ip Analytics and 22 more 2023-11-07 5.3 Medium
An Information Disclosure vulnerability exists in NTP 4.2.7p25 private (mode 6/7) messages via a GET_RESTRICT control message, which could let a malicious user obtain sensitive information.
CVE-2013-5211 3 Ntp, Opensuse, Oracle 3 Ntp, Opensuse, Linux 2023-11-01 N/A
The monlist feature in ntp_request.c in ntpd in NTP before 4.2.7p26 allows remote attackers to cause a denial of service (traffic amplification) via forged (1) REQ_MON_GETLIST or (2) REQ_MON_GETLIST_1 requests, as exploited in the wild in December 2013.
CVE-2023-26554 1 Ntp 1 Ntp 2023-04-20 5.6 Medium
mstolfp in libntp/mstolfp.c in NTP 4.2.8p15 has an out-of-bounds write when adding a '\0' character. An adversary may be able to attack a client ntpq process, but cannot attack ntpd.
CVE-2023-26553 1 Ntp 1 Ntp 2023-04-20 5.6 Medium
mstolfp in libntp/mstolfp.c in NTP 4.2.8p15 has an out-of-bounds write when copying the trailing number. An adversary may be able to attack a client ntpq process, but cannot attack ntpd.
CVE-2023-26552 1 Ntp 1 Ntp 2023-04-20 5.6 Medium
mstolfp in libntp/mstolfp.c in NTP 4.2.8p15 has an out-of-bounds write when adding a decimal point. An adversary may be able to attack a client ntpq process, but cannot attack ntpd.
CVE-2023-26551 1 Ntp 1 Ntp 2023-04-20 5.6 Medium
mstolfp in libntp/mstolfp.c in NTP 4.2.8p15 has an out-of-bounds write in the cp<cpdec while loop. An adversary may be able to attack a client ntpq process, but cannot attack ntpd.
CVE-2015-5219 10 Canonical, Debian, Fedoraproject and 7 more 20 Ubuntu Linux, Debian Linux, Fedora and 17 more 2023-02-13 7.5 High
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-2015-5195 5 Canonical, Debian, Fedoraproject and 2 more 8 Ubuntu Linux, Debian Linux, Fedora and 5 more 2023-02-13 N/A
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.
