The only generally-exploitable bug in the above list is the crypto-NAK bug,
which has a CVSS2 score of 6.4.

Additionally, three bugs that have already been fixed in ntp-4.2.8 but were
not fixed in ntp-4.2.6 as it was EOL'd have a security component, but are all
below 1.8 CVSS score, so we're reporting them here:

* Bug 2382 : Peer precision < -31 gives division by zero
* Bug 1774 : Segfaults if cryptostats enabled when built without OpenSSL
* Bug 1593 : ntpd abort in free() with logconfig syntax error
