| 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. | 5.8 |
| 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. | 5.0 |
| 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 |
| 2017-03-27 | CVE-2017-6458 | Improper Restriction of Operations within the Bounds of a Memory Buffer vulnerability in multiple products 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. | 8.8 |
| 2017-01-30 | CVE-2016-2518 | Out-of-bounds Read vulnerability in multiple products 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. | 5.0 |
| 2017-01-30 | CVE-2015-7977 | NULL Pointer Dereference vulnerability in multiple products 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. | 4.3 |
| 2017-01-30 | CVE-2015-7973 | 7PK - Security Features vulnerability in multiple products NTP before 4.2.8p6 and 4.3.x before 4.3.90, when configured in broadcast mode, allows man-in-the-middle attackers to conduct replay attacks by sniffing the network. | 5.8 |
| 2014-12-20 | CVE-2014-9296 | Code vulnerability in NTP 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. | 5.0 |
| 2014-12-20 | CVE-2014-9295 | Improper Restriction of Operations within the Bounds of a Memory Buffer vulnerability in NTP 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. | 7.5 |
| 2014-12-20 | CVE-2014-9294 | Unspecified vulnerability in NTP 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. | 7.5 |
