Description
A vulnerability was found in BIND 9 resolvers, where processing malformed DNSKEY records from a specially crafted zone can lead to resource exhaustion, primarily causing excessive CPU utilization. This issue enables a remote, unauthenticated attacker to degrade resolver performance and potentially cause a denial of service (DoS) for legitimate DNS clients.
