 NTP Bug 3011
Duplicate IPs on unconfig directives will cause an assertion botch in ntpd

    Date Resolved: Stable (4.2.8p7) 26 Apr 2016; Dev (4.3.92) 26 Apr 2016
    References: Sec 3011 / CVE-2016-2516 / 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 6.3 (AV:N/AC:M/Au:S/C:N/I:N/A:C)
    CVSS3: MED 4.2 (CVSS:3.0/AV:N/AC:H/PR:H/UI:R/S:U/C:N/I:N/A:H)
    Summary: If ntpd was expressly configured to allow for remote configuration, a malicious user who knows the controlkey for ntpq or the requestkey for ntpdc (if mode7 is expressly enabled) can create a session with ntpd and if an existing association is unconfigured using the same IP twice on the unconfig directive line, ntpd will abort.
    Mitigation:
        Implement BCP-38.
        Upgrade to 4.2.8p7, or later, from the NTP Project Download Page or the NTP Public Services Project Download Page
        Properly monitor your ntpd instances 
    Credit: This weakness was discovered by Yihan Lian of the Cloud Security Team, Qihoo 360.
