+<p>Several vulnerabilities were discovered in BIND, a DNS server
+implementation.</p>
+
+<ul>
+
+<li><a href="https://security-tracker.debian.org/tracker/CVE-2019-6477">CVE-2019-6477</a>
+
+    <p>It was discovered that TCP-pipelined queries can bypass tcp-client
+    limits resulting in denial of service.</p></li>
+
+<li><a href="https://security-tracker.debian.org/tracker/CVE-2020-8616">CVE-2020-8616</a>
+
+    <p>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.</p></li>
+
+<li><a href="https://security-tracker.debian.org/tracker/CVE-2020-8617">CVE-2020-8617</a>
+
+    <p>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.</p></li>
+
+</ul>
+
+<p>For the oldstable distribution (stretch), these problems have been fixed
+in version 1:9.10.3.dfsg.P4-12.3+deb9u6.</p>
+
+<p>For the stable distribution (buster), these problems have been fixed in
+version 1:9.11.5.P4+dfsg-5.1+deb10u1.</p>
+
+<p>We recommend that you upgrade your bind9 packages.</p>
