+	  <p>CVE-2020-10995: An issue in the DNS protocol has been found that allow malicious parties to use
+	   recursive DNS services to attack third party authoritative name servers. The attack uses a crafted
+	   reply by an authoritative name server to amplify the resulting traffic between the recursive and
+	   other authoritative name servers. Both types of service can suffer degraded performance as an effect.</p>
+	  <p>CVE-2020-12244: An issue has been found in PowerDNS Recursor 4.1.0 through 4.3.0 where records in
+	   the answer section of a NXDOMAIN response lacking an SOA were not properly validated in
+	   SyncRes::processAnswer. This would allow an attacker in position of man-in-the-middle to send a
+	   NXDOMAIN answer for a name that does exist, bypassing DNSSEC validation.</p>
+	  <p>CVE-2020-10030: An issue has been found in PowerDNS Authoritative Server allowing an attacker
+	   with enough privileges to change the system's hostname to cause disclosure of uninitialized memory
+	   content via a stack-based out-of-bounds read. It only occurs on systems where gethostname() does
+	   not null-terminate the returned string if the hostname is larger than the supplied buffer. Linux
+	   systems are not affected because the buffer is always large enough. OpenBSD systems are not affected
+	   because the returned hostname is always null-terminated. Under some conditions this issue can lead
+	   to the writing of one null-byte out-of-bounds on the stack, causing a denial of service or possibly
+	   arbitrary code execution.</p>
