Hello everyone,

We are very happy to announce the 4.1.9 release of the PowerDNS
Recursor. This release is fixing two security issues, and addressing a
shortcoming in the way incoming queries are distributed to threads under
heavy load.

This release fixes the following security issues:

- PowerDNS Security Advisory 2019-01 [1] (CVE-2019-3806): Lua hooks are
not called over TCP
- PowerDNS Security Advisory 2019-02 [2] (CVE-2019-3807): DNSSEC
validation is not performed for AA=0 responses

These issues respectively affect PowerDNS Recursor from 4.1.4 and 4.1.0,
up to and including 4.1.8. PowerDNS Recursor 4.0.x and below are not
affected.

Minimal patches are available at [3] and [4].

The changelog [5]:

- #7397: Load the Lua script in the distributor thread, check signature
for AA=0 answers (CVE-2019-3806, CVE-2019-3807)
- #7377: Try another worker before failing if the first pipe was full

The tarball [6] (signature [7]) is available at
https://downloads.powerdns.com/releases/ and packages for CentOS 6 and
7, Debian Jessie and Stretch, Ubuntu Bionic, Trusty and Xenial are
available from https://repo.powerdns.com/.

Please send us all feedback and issues you might have via the mailing
list [8], or in case of a bug, via GitHub [9].
