 NTP Bug 2978
Interleave-pivot

    Date Resolved: Stable (4.2.8p7) 26 Apr 2016; Dev (4.3.92) 26 Apr 2016
    References: Sec 2978 / CVE-2016-1548 / VU#718152
    Affects: All ntp-4 releases up to, but not including 4.2.8p7, and 4.3.0 up to, but not including 4.3.92
    CVSS2: MED 6.4 - (AV:N/AC:L/Au:N/C:N/I:P/A:P)
    CVSS3: MED 7.2 - CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:L/A:L
    Summary: It is possible to change the time of an ntpd client or deny service to an ntpd client by forcing it to change from basic client/server mode to interleaved symmetric mode. An attacker can spoof a packet from a legitimate ntpd server with an origin timestamp that matches the peer->dst timestamp recorded for that server. After making this switch, the client will reject all future legitimate server responses. It is possible to force the victim client to move time after the mode has been changed. ntpq gives no indication that the mode has been switched.
    Mitigation:
        Implement BCP-38.
        Upgrade to 4.2.8p7 from the NTP Project Download Page or the NTP Public Services Project Download Page, which prevents ntpd from dynamically enabling interleave mode.
        Properly monitor your ntpd instances 
    Credit: This weakness was discovered by Miroslav Lichvar of RedHat and separately by Jonathan Gardner of Cisco ASIG.
