Debian DSA-2385-1 : pdns - packet loop

medium Nessus Plugin ID 57525

Language:

Synopsis

The remote Debian host is missing a security-related update.

Description

Ray Morris discovered that the PowerDNS authoritative server responds to response packets. An attacker who can spoof the source address of IP packets can cause an endless packet loop between a PowerDNS authoritative server and another DNS server, leading to a denial of service.

Solution

Upgrade the pdns packages.

For the oldstable distribution (lenny), this problem has been fixed in version 2.9.21.2-1+lenny1.

For the stable distribution (squeeze), this problem has been fixed in version 2.9.22-8+squeeze1.
