non-security bug :

CVE-2015-3294: A remote unauthenticated attacker could have caused a
denial of service (DoS) or read memory from the heap, potentially
disclosing information such as performed DNS queries or encryption
keys. (bsc#928867)

bsc#923144: When answer to an upstream query is a CNAME pointing to an
A/AAAA record which is present locally (/etc/hosts), allow caching
when the upstream and local A/AAAA records have the same value.

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."
