Description:	Summary: The remote host is missing an update for the 'pdns' package(s) announced via the MGASA-2019-0008 advisory. Vulnerability Insight: A vulnerability was in found in PowerDNS Authoritative Server. 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 an authorized user to cause a denial of service by inserting specially crafted records in a zone under their control, then sending DNS queries for that zone (CVE-2018-10851). An issue has been found in PowerDNS Authoritative Server 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 DNSSEC validating clients will consider the answer to be bogus until it expires from the packet cache, leading to a denial of service (CVE-2018-14626). Affected Software/OS: 'pdns' package(s) on Mageia 6. Solution: Please install the updated package(s). CVSS Score: 5.0 CVSS Vector: AV:N/AC:L/Au:N/C:N/I:N/A:P
