Adam Dobrawy, Frederico Silva and Gregory Brzeski from HyperOne.com discovered that pdns, an authoritative DNS server, did not properly validate user-supplied data when building a HTTP request from a DNS query in the HTTP Connector of the Remote backend. This would allow a remote user to cause either a denial-of-service, or information disclosure. For the stable distribution (stretch), this problem has been fixed in version 4.0.3-1+deb9u4. We recommend that you upgrade your pdns packages. For the detailed security status of pdns please refer to its security tracker page at: https://security-tracker.debian.org/tracker/pdns
