Name of the Vulnerable Software and Affected Versions: PowerDNS Recursor versions prior to 4.0.8

Description: The issue is related to the parsing of authoritative answers, which can lead to a denial of service when an unauthenticated remote attacker sends a specially crafted answer containing a CNAME of a different class than IN. This results in a NULL pointer dereference.

Recommendations: For versions prior to 4.0.8, update to version 4.0.8 or later to resolve the issue.
