67b845fcc9 ntp: security bump to version 4.2.8p1
Fixes:

CVE-2014-9297 - vallen is not validated in several places in ntp_crypto.c,
leading to a potential information leak or possibly a crash

CVE-2014-9298 - ::1 can be spoofed on some OSes (including "some versions" of
Linux), so ACLs based on IPv6 ::1 addresses can be bypassed

Drop a patch applied upstream, along with its accompanied AUTORECONF.

5d5c9a8dcb ntp: security bump to version 4.2.8
Fixes:

CVE-2014-9293 - ntpd generated a weak key for its internal use, with
full administrative privileges.  Attackers could use this key to
reconfigure ntpd (or to exploit other vulnerabilities).

CVE-2014-9294 - The ntp-keygen utility generated weak MD5 keys with
insufficient entropy.

CVE-2014-9295 - ntpd had several buffer overflows (both on the stack and
in the data section), allowing remote authenticated attackers to crash
ntpd or potentially execute arbitrary code.

CVE-2014-9296 - The general packet processing function in ntpd did not
handle an error case correctly.
