Title: PowerDNS: Denial of Service vulnerability (GLSA 200502-15)
Date: February 13, 2005
Updated: May 22, 2006
A vulnerability in PowerDNS could lead to a temporary Denial of Service.
The PowerDNS Nameserver is an authoritative-only nameserver which uses a flexible backend architecture.
Vulnerable: < 2.9.17
Unaffected: >= 2.9.17
Architectures: All supported architectures
A vulnerability has been reported in the DNSPacket::expand method of dnspacket.cc.
An attacker could cause a temporary Denial of Service by sending a random stream of bytes to the PowerDNS Daemon.
There is no known workaround at this time.
All PowerDNS users should upgrade to the latest version:
|# emerge --sync
# emerge --ask --oneshot --verbose ">=net-dns/pdns-2.9.17"
