73
	  <p>CVE-2020-10995: An issue in the DNS protocol has been found that allow malicious parties to use
74
	   recursive DNS services to attack third party authoritative name servers. The attack uses a crafted
75
	   reply by an authoritative name server to amplify the resulting traffic between the recursive and
76
	   other authoritative name servers. Both types of service can suffer degraded performance as an effect.</p>
77
	  <p>CVE-2020-12244: An issue has been found in PowerDNS Recursor 4.1.0 through 4.3.0 where records in
78
	   the answer section of a NXDOMAIN response lacking an SOA were not properly validated in
79
	   SyncRes::processAnswer. This would allow an attacker in position of man-in-the-middle to send a
80
	   NXDOMAIN answer for a name that does exist, bypassing DNSSEC validation.</p>
81
	  <p>CVE-2020-10030: An issue has been found in PowerDNS Authoritative Server allowing an attacker
82
	   with enough privileges to change the system's hostname to cause disclosure of uninitialized memory
83
	   content via a stack-based out-of-bounds read. It only occurs on systems where gethostname() does
84
	   not null-terminate the returned string if the hostname is larger than the supplied buffer. Linux
85
	   systems are not affected because the buffer is always large enough. OpenBSD systems are not affected
86
	   because the returned hostname is always null-terminated. Under some conditions this issue can lead
87
	   to the writing of one null-byte out-of-bounds on the stack, causing a denial of service or possibly
88
	   arbitrary code execution.</p>
