Alpine: multiple pdns-recursor packages: security update to 4.2.2-r0
high Tenable Cloud Security Plugin ID 406256
Description
There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:- PowerDNS Recursor from 4.1.0 up to and including 4.3.0 does not sufficiently defend against amplification
attacks. An issue in the DNS protocol has been found that allow malicious parties to use recursive DNS
services to attack third party authoritative name servers. The attack uses a crafted reply by an
authoritative name server to amplify the resulting traffic between the recursive and other authoritative
name servers. Both types of service can suffer degraded performance as an effect. This is triggered by
random subdomains in the NSDNAME in NS records. PowerDNS Recursor 4.1.16, 4.2.2 and 4.3.1 contain a
mitigation to limit the impact of this DNS protocol issue. (CVE-2020-10995)
- An issue has been found in PowerDNS Recursor 4.1.0 through 4.3.0 where records in the answer section of a
NXDOMAIN response lacking an SOA were not properly validated in SyncRes::processAnswer, allowing an
attacker to bypass DNSSEC validation. (CVE-2020-12244)
