Overview
Affected versions of this package are vulnerable to Infinite loop via the dns_copy_qname function. An attacker can cause the system to enter an infinite loop by sending specially crafted DNS queries that cause the assignment of "pos" to be assigned to the same value it already contains, or a chain of pos assignments jumping back and forth causing the same position to be visited again.
