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.
VPR Score: 3.6
Synopsis
The remote device is missing a vendor-supplied security patch.
Description
named in ISC BIND 9.x before 9.9.9-P5, 9.10.x before 9.10.4-P5, and 9.11.x before 9.11.0-P2 allows remote attackers to cause a denial of service (assertion failure and daemon exit) via a crafted DS resource record in an answer.(CVE-2016-9444)
Impact
When the BIND recursion option is enabled, an attacker may 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 DNS or GTM systems. If the BIND recursion option is enabled, BIG-IP DNS or GTM systems are vulnerable.
Solution
Upgrade to one of the non-vulnerable versions listed in the F5 Solution K40181790.
