Description

The nameserver bind was updated to fix a remote denial of service (crash) attack against bind nameservers doing validation on DNSSEC signed records. (CVE-2015-5722, bsc#944066).

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.
