Debian DSA-4424-1 : pdns - security update

high Nessus Plugin ID 123758

Synopsis

The remote Debian host is missing a security-related update.

Description

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.

Solution

Upgrade the pdns packages.

For the stable distribution (stretch), this problem has been fixed in version 4.0.3-1+deb9u4.
