Alpine: multiple pdns-recursor packages: security update to 4.1.8-r0

high Tenable Cloud Security Plugin ID 406254

Description

There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

- PowerDNS Authoritative Server 3.3.0 up to 4.1.4 excluding 4.1.5 and 4.0.6, and PowerDNS Recursor 3.2 up to
4.1.4 excluding 4.1.5 and 4.0.9, are vulnerable to a memory leak while parsing malformed records that can
lead to remote denial of service. (CVE-2018-10851)

- PowerDNS Authoritative Server 4.1.0 up to 4.1.4 inclusive and PowerDNS Recursor 4.0.0 up to 4.1.4
inclusive are vulnerable to a packet cache pollution via crafted query that can lead to denial of service.
(CVE-2018-14626)

- An issue has been found in PowerDNS Recursor from 4.0.0 up to and including 4.1.4. A remote attacker
sending a DNS query for a meta-type like OPT can lead to a zone being wrongly cached as failing DNSSEC
validation. It only arises if the parent zone is signed, and all the authoritative servers for that parent
zone answer with FORMERR to a query for at least one of the meta-types. As a result, subsequent queries
from clients requesting DNSSEC validation will be answered with a ServFail. (CVE-2018-14644)

- An issue has been found in PowerDNS Recursor before version 4.1.8 where a remote attacker sending a DNS
query can trigger an out-of-bounds memory read while computing the hash of the query for a packet cache
lookup, possibly leading to a crash. (CVE-2018-16855)
