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.
