Debian DSA-3096-1 : pdns-recursor - security update

medium Nessus Plugin ID 79883

Language:

Synopsis

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

Description

Florian Maury from ANSSI discovered a flaw in pdns-recursor, a recursive DNS server : a remote attacker controlling maliciously-constructed zones or a rogue server could affect the performance of pdns-recursor, thus leading to resource exhaustion and a potential denial-of-service.

Solution

Upgrade the pdns-recursor packages.

For the stable distribution (wheezy), this problem has been fixed in version 3.3-3+deb7u1.

For the upcoming stable distribution (jessie) and unstable distribution (sid), this problem has been fixed in version 3.6.2-1.
