CVE-2016-4955

CVE-2016-4955 affects ntpd (NTP 4.x) prior to 4.2.8p8. When autokey is enabled, a remote attacker can cause a denial of service by sending a spoofed CRYPTO_NAK packet or a packet with an incorrect MAC at a specific time, which can trigger autokey association reset. Cloud/OS advisories confirm thi...

CVE-2016-4954

The CVE-2016-4954 entry affects ntpd (NTP v4) and is triggered by the process_packet() function in ntp_proto.c, where NTP 4.x versions before 4.2.8p8 can be caused to enter a peer-variable modification state when it receives spoofed packets from multiple sources, demonstrated by an incorrect leap...

CVE-2016-4956

ntpd (NTP 4.x) before 4.2.8p8 is vulnerable to DoS via a spoofed broadcast packet, triggering interleaved-mode transitions and time changes. This exists due to an incomplete fix for CVE-2016-1548. Exploitation can disrupt time synchronization, with public advisories linking the issue to broadcast...
