+ <p>CVE-2018-10851: An issue has been found in PowerDNS Recursor allowing
+ a malicious authoritative server to cause a memory leak by sending specially
+ crafted records. The issue is due to the fact that some memory is allocated
+ before the parsing and is not always properly released if the record is malformed.
+ When the PowerDNS Recursor is run inside a supervisor like supervisord or systemd,
+ an out-of-memory crash will lead to an automatic restart, limiting the impact to
+ a somewhat degraded service.</p>
+ <p>CVE-2018-14626: An issue has been found in PowerDNS Recursor allowing a remote
+ user to craft a DNS query that will cause an answer without DNSSEC records to be
+ inserted into the packet cache and be returned to clients asking for DNSSEC
+ records, thus hiding the presence of DNSSEC signatures for a specific qname and
+ qtype. For a DNSSEC-signed domain, this means that clients performing DNSSEC
+ validation by themselves might consider the answer to be bogus until it expires
+ from the packet cache, leading to a denial of service.</p>
+ <p>CVE-2018-14644: An issue has been found in PowerDNS Recursor where a remote attacker
+ sending a DNS query for a meta-type like OPT can lead to a zone being wrongly cached
+ as failing DNSSEC validation. It only arises if the parent zone is signed, and all
+ the authoritative servers for that parent zone answer with FORMERR to a query for at
+ least one of the meta-types. As a result, subsequent queries from clients requesting
+ DNSSEC validation will be answered with a ServFail.</p>
