CVE-2020-25829: Opensuse Backports Sle

High severity, CVSS 7.5. EPSS: 6.5% chance of exploitation in the next 30 days.

An issue has been found in PowerDNS Recursor before 4.1.18, 4.2.x before 4.2.5, and 4.3.x before 4.3.5. 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 (dnssec=process).

Affected products

• Opensuse Backports Sle: version 15.0 only
• Opensuse Leap: version 15.1 only; version 15.2 only
• Powerdns Recursor: before 4.1.18 (fixed in 4.1.18); from 4.2.0, before 4.2.5 (fixed in 4.2.5); from 4.3.0, before 4.3.5 (fixed in 4.3.5)
