Description
Updated pdns packages fix security vulnerability PowerDNS Authoritative Server accepts queries with a qname's length larger than 255 bytes (CVE-2016-5426). PowerDNS Authoritative Server does not properly handle dot inside labels (CVE-2016-5427). These issues allow a remote, unauthenticated attacker to cause an abnormal load on the PowerDNS backend by sending crafted DNS queries, which might result in a partial denial of service if the backend becomes overloaded. It was found that PowerDNS does not implement reasonable restrictions for zone sizes. This allows an explicitly configured primary DNS server for a zone to crash a secondary DNS server, affecting service of other zones hosted on the same secondary server (CVE-2016-6172).
