 NTP Bug 3008
ctl_getitem() return value not always checked

    Date Resolved: Stable (4.2.8p7) 26 Apr 2016; Dev (4.3.92) 26 Apr 2016
    References: Sec 3008 / CVE-2016-2519 / 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 4.9 (AV:N/AC:H/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: ntpq and ntpdc can be used to store and retrieve information in ntpd. It is possible to store a data value that is larger than the size of the buffer that the ctl_getitem() function of ntpd uses to report the return value. If the length of the requested data value returned by ctl_getitem() is too large, the value NULL is returned instead. There are 2 cases where the return value from ctl_getitem() was not directly checked to make sure it's not NULL, but there are subsequent INSIST() checks that make sure the return value is not NULL. There are no data values ordinarily stored in ntpd that would exceed this buffer length. But if one has permission to store values and one stores a value that is "too large", then ntpd will abort if an attempt is made to read that oversized value.
    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
