Comment 2 Reinhard Max 2015-11-06 13:50:37 UTC 
The patch applied to SLE-12-GA (ntp-4.2.6p5) with minor changes, but it doesn't seem to fit SLE-11-SP1 (ntp-4.2.4p8) at all, where KoD handling seems to be entirely different.

Hello Mr. Max,

any chances that a patch will be available for openSUSE 13.1?
Version 4.2.6p5 is available there but no entry in the changelog with these CVEs and I couldn't find an according patch in Yast.
Thank you for your time.

Kind regards,
Ronny Peine
Comment 4 Reinhard Max 2016-05-03 17:10:14 UTC 
Sorry, I didn't get around to do it for 13.1 and meanwhile it has ran out of official maintenance.

But the fix is part of ntp-4.2.8p7, which we will soon release for 13.2, 42.1 and all maintained SLE versions.
