bind9: Preparing an NSEC3 closest encloser proof can exhaust CPU resources

A flaw was found in bind9. By flooding a DNSSEC resolver with responses coming from a DNSEC-signed zone using NSEC3, an attacker can lead the targeted resolver to a CPU exhaustion, further leading to a Denial of Service on the targeted host. This vulnerability applies only for systems where DNSSE...
