Debian: DSA-2515-1 Moderate: NSD3 Null Pointer Denial of Service

Marek Vavruša and Lubos Slovak discovered that NSD, an authoritative
domain name server, is not properly handling non-standard DNS packets.
his can result in a NULL pointer dereference and crash the handling
process. A remote attacker can abuse this flaw to perform denial of
service attacks.

version 3.2.5-1.squeeze2.
