NSD 'packet.c' Off-By-One Buffer Overflow Vulnerability

Summary
NSD is prone to an off-by-one buffer-overflow vulnerability because the server fails to perform adequate boundary checks on user-supplied data. Successfully exploiting this issue will allow attackers to execute arbitrary code within the context of the affected server. Failed exploit attempts will result in a denial-of-service condition. Versions prior to NSD 3.2.2 are vulnerable.
Solution
The vendor has released fixes. Please see http://www.nlnetlabs.nl/projects/nsd/ for more information.
