NTP users are strongly urged to take immediate action to ensure that their NTP daemons are not susceptible to being used in distributed denial-of-service (DDoS) attacks. Please also take this opportunity to defeat denial-of-service attacks by implementing Ingress and Egress filtering through BCP38.

ntp-4.2.8p10 was released on 21 March 2017. It addresses 6 medium- and 5 low-severity security issues, 4 informational security topics, 15 bugfixes, and contains other improvements over 4.2.8p9.

Please see the NTP Security Notice for vulnerability and mitigation details.

Are you using Autokey in production? If so, please contact Harlan - he's got some questions for you.

Discussion

Make sntp a component of ntp?

Once upon a time we decided there were Good Reasons to have the SNTP code be a separate bugzilla product from the NTP code.

Now that we have a new sntp implementation and as time passes we will likely be sharing more and more code between these two codebases Harlan is thinking that it might be overall easier to have any SNTP issues handled by a component under the NTP bugzilla product.


MHO: Toss the current SNTP client, it reeks. It violates RFC, has no maintainer, Dave dislikes it, toast it. Rename the gsoc_sntp to sntp and go forward without the old one. As far as code base, I would prefer to see it independent of the ntp distro. Yes, there are some code reuse issues, but the independence, and the simplicity, of the new SNTP client, make up for the duplication. .02

Rob, we will be deleting the old/current SNTP client and using the gsoc_sntp client, perhaps as soon as 4.2.6. At that time we'll be renaming the subdir from gsoc_sntp to sntp.

The sntp/ subdir will produce a stand-alone source code tarball.

And separate from all of this is the issue of "should ntp and sntp be separate bugzilla products, or should we just use a single ntp product and have sntp be a separate compoment?" I'm leaning toward the latter.
