Arch Linux Security Advisory ASA-201412-9
Date : 2014-12-09
CVE-ID : CVE-2014-8601
Package : powerdns-recursor
Type : denial of service
Remote : Yes
Link : https://wiki.archlinux.org/index.php/CVE-2014
The package powerdns-recursor before version 3.6.2-1 is vulnerable to
remote denial of service.
Upgrade to 3.6.2-1.
# pacman -Syu "powerdns-recursor>=3.6.2-1"
The problem has been fixed upstream in version 3.6.2.
Only clients in allow-from are able to trigger the degraded service, so
this should be limited to your user base.
PowerDNS, while acting as a caching nameserver, can be negatively
impacted by sending queries for specially configured, hard to resolve
domain names. This is the same issue as the ones found in bind
(ASA-201412-7) and unbound (ASA-201412-8).
A remote attacker can trick unbound into consuming a lot of resources by
sending a specially crafted query.
