PowerDNS Team reports:

+
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.
+
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.
+
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.
