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. NOTE: this vulnerability exists because of an incomplete fix for CVE-2016-1548. Mitigation Do not use NTPs broadcast mode in the clients ...

Medium: ntp

Issue Overview: It was found that an ntpd client could be forced to change from basic client/server mode to the interleaved symmetric mode. A remote attacker could use a spoofed packet that, when processed by an ntpd client, would cause that client to reject all future legitimate server responses...
