Description

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.
