The PowerDNS project reports:

A bug was discovered in our label decompression code, making it
possible for names to refer to themselves, thus causing a loop during
decompression. On some platforms, this bug can be abused to cause
crashes. On all platforms, this bug can be abused to cause
service-affecting CPU spikes.
