DATE | CVE | VULNERABILITY TITLE | RISK |
---|---|---|---|
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 |
2018-06-20 | CVE-2018-12327 | Out-of-bounds Write vulnerability in NTP 4.2.8 Stack-based buffer overflow in ntpq and ntpdc of NTP version 4.2.8p11 allows an attacker to achieve code execution or escalate to higher privileges via a long string as the argument for an IPv4 or IPv6 command-line parameter. | 7.5 |
2018-06-04 | CVE-2016-9042 | Improper Input Validation vulnerability in multiple products An exploitable denial of service vulnerability exists in the origin timestamp check functionality of ntpd 4.2.8p9. | 5.9 |
2018-03-08 | CVE-2018-7183 | Out-of-bounds Write vulnerability in multiple products Buffer overflow in the decodearr function in ntpq in ntp 4.2.8p6 through 4.2.8p10 allows remote attackers to execute arbitrary code by leveraging an ntpq query and sending a response with a crafted array. | 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. | 5.0 |
2018-03-06 | CVE-2018-7184 | ntpd in ntp 4.2.8p4 before 4.2.8p11 drops bad packets before updating the "received" timestamp, which allows remote attackers to cause a denial of service (disruption) by sending a packet with a zero-origin timestamp causing the association to reset and setting the contents of the packet as the most recent timestamp. | 5.0 |
2018-03-06 | CVE-2018-7182 | Out-of-bounds Read vulnerability in multiple products The ctl_getitem method in ntpd in ntp-4.2.8p6 before 4.2.8p11 allows remote attackers to cause a denial of service (out-of-bounds read) via a crafted mode 6 packet with a ntpd instance from 4.2.8p6 through 4.2.8p10. | 5.0 |
2018-03-06 | CVE-2018-7170 | Unspecified vulnerability in NTP 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. | 3.5 |
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. | 3.5 |
2017-08-09 | CVE-2015-3405 | Insufficient Entropy vulnerability in multiple products 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. | 7.5 |
