CVE-2018-14626 [MEDIUM] CVE-2018-14626 pdns: Packet cache pollution via crafted query
CVE-2018-14626 pdns: Packet cache pollution via crafted query
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.
