The flaw allows a malicious client to exploit the DNSSEC validation process by sending a stream of SIG(0) signed requests, leading to CPU exhaustion on the resolver. This can cause a denial-of-service (DoS), rendering the DNS server unable to respond to legitimate queries. Given the widespread use of BIND9 in both enterprise and public DNS infrastructure, the impact of such an attack can be extensive, affecting numerous users and services reliant on DNS resolution.", "threat_severity": "Important"}
