New! Vulnerability Priority Rating (VPR)
Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.

SynopsisThe remote device is missing a vendor-supplied security patch.
Descriptionnamed in ISC BIND 9.9.9-P4, 9.9.9-S6, 9.10.4-P4, and 9.11.0-P1 allows remote attackers to cause a denial of service (assertion failure and daemon exit) via a response containing an inconsistency among the DNSSEC-related RRsets. (CVE-2016-9147)
When the BIND recursion option is enabled, an attacker can exploit this vulnerability to cause the named process to restart.
Additionally, the restarted process does not trigger the BIG-IP system high availability (HA) failover event.
By default, the BIND recursion option is not enabled on BIG-IP DNSsystems. If the BIND recursion option is enabled, BIG-IP DNS systems are vulnerable.
