bind9
dnssec resolver
cpu exhaustion
denial of service
nsec3
dnssec validation
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 DNSSEC validation is enabled.
Mitigation
There are no mitigations for this issue that meet Red Hat's secure workaround criteria. Updating the package to the version containing the fix is recommended.
