Package        : pdns
CVE ID         : CVE-2019-3871
Debian Bug     : 924966

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

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
