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 is different from CVSS.

Synopsis
The remote Debian host is missing a security update.Description
Several denial of service vulnerabilities (assertion failures) were discovered in BIND, a DNS server implementation.CVE-2016-9131
A crafted upstream response to an ANY query could cause an assertion failure.
CVE-2016-9147
A crafted upstream response with self-contradicting DNSSEC data could cause an assertion failure.
CVE-2016-9444
Specially crafted upstream responses with a DS record could cause an assertion failure.
These vulnerabilities predominantly affect DNS servers providing recursive service. Client queries to authoritative-only servers cannot trigger these assertion failures. These vulnerabilities are present whether or not DNSSEC validation is enabled in the server configuration.
For Debian 7 'Wheezy', these problems have been fixed in version 1:9.8.4.dfsg.P1-6+nmu2+deb7u14.
We recommend that you upgrade your bind9 packages.
NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
