 NTP Bug 3042
Broadcast interleave

    Date Resolved: 02 June 2016; Dev (4.3.93) 02 June 2016
    References: Sec 3042 / CVE-2016-4956 / VU#321640
    Affects: ntp-4, up to but not including ntp-4.2.8p8, and ntp-4.3.0 up to, but not including ntp-4.3.93.
    CVSS2: LOW 2.6 (AV:N/AC:H/Au:N/C:N/I:N/A:P)
    CVSS3: LOW 3.7 CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:L
    Summary: The fix for NtpBug2978 does not cover broadcast associations, so broadcast clients can be triggered to flip into interleave mode.
    Mitigation:
        Implement BCP-38.
        Upgrade to 4.2.8p8, or later, from the NTP Project Download Page or the NTP Public Services Project Download Page
        Properly monitor your ntpd instances.
