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.

Synopsis
The remote Debian host is missing a security update.
Description
Several vulnerabilities were discovered in BIND, a DNS server implementation.
CVE-2020-8616
It was discovered that BIND does not sufficiently limit the number of fetches performed when processing referrals. An attacker can take advantage of this flaw to cause a denial of service (performance degradation) or use the recursing server in a reflection attack with a high amplification factor.
CVE-2020-8617
It was discovered that a logic error in the code which checks TSIG validity can be used to trigger an assertion failure, resulting in denial of service.
For Debian 8 'Jessie', these problems have been fixed in version 1:9.9.5.dfsg-9+deb8u19.
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.
Solution
Upgrade the affected packages.
