CVE-2016-4955

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...

CVE-2016-4954

The processpacket function in ntpproto.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...

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-2016-4957

ntpd (NTP) before version 4.2.8p8 is vulnerable to a remote DoS via specially crafted crypto-NAK packets, causing ntpd to crash. This issue stems from an incorrect fix applied after CVE-2016-1547 and affects ntpd’s handling of CRYPTO-NAK. Public references indicate an impact to the daemon’s avail...

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...
