| DATE | CVE | VULNERABILITY TITLE | RISK |
|---|---|---|---|
| 2020-06-04 | CVE-2020-13817 | Use of Insufficiently Random Values vulnerability in multiple products 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. | 7.4 |
| 2020-04-17 | CVE-2020-11868 | Origin Validation Error vulnerability in multiple products 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. | 7.5 |
| 2020-01-28 | CVE-2015-7851 | Path Traversal vulnerability in NTP Directory traversal vulnerability in the save_config function in ntpd in ntp_control.c in NTP before 4.2.8p4, when used on systems that do not use '\' or '/' characters for directory separation such as OpenVMS, allows remote authenticated users to overwrite arbitrary files. | 6.5 |
| 2020-01-08 | CVE-2014-5209 | Information Exposure vulnerability in multiple products 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. | 5.3 |
| 2019-05-15 | CVE-2019-8936 | NULL Pointer Dereference vulnerability in multiple products NTP through 4.2.8p12 has a NULL Pointer Dereference. | 7.5 |
| 2018-03-06 | CVE-2018-7185 | The protocol engine in ntp 4.2.6 before 4.2.8p11 allows a remote attackers to cause a denial of service (disruption) by continually sending a packet with a zero-origin timestamp and source IP address of the "other side" of an interleaved association causing the victim ntpd to reset its association. | 7.5 |
| 2018-03-06 | CVE-2018-7170 | ntpd in ntp 4.2.x before 4.2.8p7 and 4.3.x before 4.3.92 allows authenticated users that know the private symmetric key to create arbitrarily-many ephemeral associations in order to win the clock selection of ntpd and modify a victim's clock via a Sybil attack. | 5.3 |
| 2017-08-24 | CVE-2015-5146 | Improper Input Validation vulnerability in multiple products 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. | 5.3 |
| 2017-08-07 | CVE-2015-7871 | Improper Authentication vulnerability in multiple products 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. | 9.8 |
| 2017-08-07 | CVE-2015-7855 | Improper Input Validation vulnerability in multiple products The decodenetnum 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 (assertion failure) via a 6 or mode 7 packet containing a long data value. | 6.5 |
