This security issue was fixed :

  - CVE-2015-5477: Remote DoS via TKEY queries (bsc#939567)

Exposure to this issue can not be prevented by either ACLs or
configuration options limiting or denying service because the
exploitable code occurs early in the packet handling.

Note that Tenable Network Security has extracted the preceding
description block directly from the SUSE security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."
