Description:Summary:
The remote host is missing an update for the 'bind9'
package(s) announced via the DSA-4689-1 advisory.

Vulnerability Insight:
Several vulnerabilities were discovered in BIND, a DNS server
implementation.

CVE-2019-6477
It was discovered that TCP-pipelined queries can bypass tcp-client
limits resulting in denial of service.

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.

Affected Software/OS:
'bind9' package(s) on Debian Linux.

Solution:
For the oldstable distribution (stretch), these problems have been fixed
in version 1:9.10.3.dfsg.P4-12.3+deb9u6.

For the stable distribution (buster), these problems have been fixed in
version 1:9.11.5.P4+dfsg-5.1+deb10u1.

We recommend that you upgrade your bind9 packages.
