I just saw this:

https://ics-cert.us-cert.gov/advisories/ICSA-14-353-01

which includes this: " A remote attacker can send a carefully crafted packet that can overflow a stack buffer and potentially allow malicious code to be executed with the privilege level of the ntpd process. All NTP4 releases before 4.2.8 are vulnerable."

"This vulnerability is resolved with NTP-stable4.2.8 on December 19, 2014."

I guess no one has had time to respond yet. Wonder if I should shut down my external NTP services as a precaution?

From the description in the Red Hat advisory and this link

http://www.kb.cert.org/vuls/id/852879 it seems the buffer overflow issues can only be exploitet with specific authentication settings that are not part of the default configuration or am I interpreting this wrong?
