Mageia: 2019-0009 Moderate: PowerDNS Recursor Denial of Service

A vulnerability was in found in PowerDNS Recursor. The issue is a memory leak occurring while parsing some malformed records, due to the fact that some memory is allocated parsing a record and is not always properly released if the record is not valid. It allows a malicious auth server to cause a denial of service by sending specially crafted records in response to a legitimate query by an authorized user (CVE-2018-10851).
