A Secunia Advisory reports:

An error exists in the handling of DNS queries where IDs are incremented with a fixed value and are additionally used for child processes in a forking server. This can be exploited to poison the DNS cache of an application using the module if a valid ID is guessed.

An error in the PP implementation within the "dn_expand()" function can be exploited to cause a stack overflow due to an endless loop via a specially crafted DNS packet.
