|Gentoo Linux Security Advisory
Title: PowerDNS: Denial of Service (GLSA 201202-04)
Date: February 22, 2012
A vulnerability in PowerDNS could allow a remote attacker to create
a Denial of Service condition.
The PowerDNS nameserver is an authoritative-only nameserver which uses a
flexible backend architecture.
Vulnerable: < 3.0.1
Unaffected: >= 3.0.1
Architectures: All supported architectures
A vulnerability has been found in PowerDNS which could cause a packet
loop of DNS responses.
A remote attacker could send specially crafted DNS response packets,
possibly resulting in a Denial of Service condition.
PowerDNS users can set "cache-ttl=0" in /etc/powerdns/pdns.conf and then
restart the PowerDNS daemon:
Please review the PowerDNS Security Advisory below for more workaround
|# /etc/init.d/pdns restart
All PowerDNS users should upgrade to the latest version:
|# emerge --sync
# emerge --ask --oneshot --verbose ">=net-dns/pdns-3.0.1"
