This update for bind fixes the following issues :

  • A defect in BIND’s handling of responses containing a DNAME answer had the potential to trigger assertion errors in the server remotely, thereby facilitating a denial-of-service attack. (CVE-2016-8864, bsc#1007829).

  • Fix BIND to return a valid hostname in response to ldapdump queries. (bsc#965748)

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.
