| DATE | CVE | VULNERABILITY TITLE | RISK |
|---|---|---|---|
| 2016-07-05 | CVE-2016-4956 | 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. | 5.3 |
| 2016-07-05 | CVE-2016-4955 | Race Condition vulnerability in multiple products 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. | 5.9 |
| 2016-07-05 | CVE-2016-4954 | Race Condition vulnerability in multiple products 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. | 7.5 |
| 2016-07-05 | CVE-2016-4953 | Improper Authentication vulnerability in multiple products ntpd in NTP 4.x before 4.2.8p8 allows remote attackers to cause a denial of service (ephemeral-association demobilization) by sending a spoofed crypto-NAK packet with incorrect authentication data at a certain time. | 5.0 |
| 2016-01-26 | CVE-2015-7974 | Improper Authentication vulnerability in multiple products NTP 4.x before 4.2.8p6 and 4.3.x before 4.3.90 do not verify peer associations of symmetric keys when authenticating packets, which might allow remote attackers to conduct impersonation attacks via an arbitrary trusted key, aka a "skeleton key." | 4.0 |
| 2015-10-06 | CVE-2014-9751 | Improper Input Validation vulnerability in multiple products The read_network_packet function in ntp_io.c in ntpd in NTP 4.x before 4.2.8p1 on Linux and OS X does not properly determine whether a source IP address is an IPv6 loopback address, which makes it easier for remote attackers to spoof restricted packets, and read or write to the runtime state, by leveraging the ability to reach the ntpd machine's network interface with a packet from the ::1 address. | 6.8 |
| 2015-10-06 | CVE-2014-9750 | Improper Input Validation vulnerability in NTP ntp_crypto.c in ntpd in NTP 4.x before 4.2.8p1, when Autokey Authentication is enabled, allows remote attackers to obtain sensitive information from process memory or cause a denial of service (daemon crash) via a packet containing an extension field with an invalid value for the length of its value field. | 5.8 |
| 2015-04-08 | CVE-2015-1799 | Code vulnerability in NTP The symmetric-key feature in the receive function in ntp_proto.c in ntpd in NTP 3.x and 4.x before 4.2.8p2 performs state-variable updates upon receiving certain invalid packets, which makes it easier for man-in-the-middle attackers to cause a denial of service (synchronization loss) by spoofing the source IP address of a peer. | 4.3 |
| 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 |
