Summary:	The remote host is missing an update for the Debian 'bind9' package(s) announced via the DLA-2227-1 advisory.
Description:	Summary: The remote host is missing an update for the Debian 'bind9' package(s) announced via the DLA-2227-1 advisory. Vulnerability Insight: 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.
