What is CVE-2016-1286?

A vulnerability in ISC's BIND versions before 9.9.8-P4 and 9.10.x before 9.10.3-P4 can be exploited by remote attackers to trigger a denial of service. This issue arises from improper handling of crafted signature records for DNAME records, resulting in assertion failures and ultimately leading to the BIND daemon exiting unexpectedly. This impacts the reliability and availability of DNS services, potentially disrupting connections for users relying on the affected servers.
