A security issue affects the following Ubuntu releases:

Ubuntu 5.10 Ubuntu 6.06 LTS Ubuntu 6.10

This advisory also applies to the corresponding versions of Kubuntu, Edubuntu, and Xubuntu.

The problem can be corrected by upgrading your system to the following package versions:

Ubuntu 5.10:
avahi-daemon 0.5.2-1ubuntu1.4

Ubuntu 6.06 LTS:
avahi-daemon 0.6.10-0ubuntu3.4

Ubuntu 6.10:
avahi-daemon 0.6.13-2ubuntu2.4

In general, a standard system upgrade is sufficient to effect the necessary changes.

Details follow:

A flaw was discovered in Avahi's handling of compressed DNS packets. If a specially crafted reply were received over the network, the Avahi daemon would go into an infinite loop, causing a denial of service.
