An insufficient validation of data coming from the user when building a HTTP request from a DNS query in the HTTP Connector of the Remote backend, allowing a remote user to cause a denial of service by making the server connect to an invalid endpoint, or possibly information disclosure by making the server connect to an internal endpoint and somehow extracting meaningful information about the response.

Only installations using the pdns-backend-remote package are affected.

For Debian 8 Jessie, this problem has been fixed in version 3.4.1-4+deb8u9.

We recommend that you upgrade your pdns packages.
