[ASA-202010-6] powerdns-recursor: denial of service
Arch Linux Security Advisory ASA-202010-6 ========================================= Severity: High Date : 2020-10-18 CVE-ID : CVE-2020-25829 Package : powerdns-recursor Type : denial of service Remote : Yes Link : Summary ======= The package powerdns-recursor before version 4.3.5-1 is vulnerable to denial of service. Resolution ========== Upgrade to 4.3.5-1. # pacman -Syu "powerdns-recursor>=4.3.5-1" The problem has been fixed upstream in version 4.3.5. Workaround ========== None. Description =========== An issue has been found in PowerDNS Recursor before 4.3.5 where 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 installations that always validate (dnssec=validate) and for clients requesting validation when on-demand validation is enabled (dnssec=process). Impact ====== A remote attacker can deny DNSSEC validation by updating the state of cached entries. References ==========
