Debian 10 Buster DLA-3855-1 Moderate: Pdns-Recursor DoS Threats

CVE-2020-14196

The ACL restricting access to the internal web server is not properly
enforced.

CVE-2020-25829

A remote attacker can cause the cached records for a given name to be
updated to the Bogus DNSSEC validation state, instead of their actual
DNSSEC Secure state, via a DNS ANY query. This results in a denial of
service for installation that always validate (dnssec=validate), and
for clients requesting validation when on-demand validation is enabled.

For Debian 10 buster, these problems have been fixed in version
4.1.11-1+deb10u2.

We recommend that you upgrade your pdns-recursor packages.
