------------------------------------------------------------------------- Debian LTS Advisory DLA-3855-1 debian-lts@lists.debian.org https://www.debian.org/lts/security/ ; Daniel Leidert July 01, 2024 https://wiki.debian.org/LTS ------------------------------------------------------------------------- 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.
