Package : pdns-recursor
Version : 4.1.11-1+deb10u2
CVE ID : CVE-2020-14196 CVE-2020-25829
Debian Bug : 964103 972159
Brief introduction
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.
