Processing specially crafted responses coming from DNSSEC-signed zones can lead to uncontrolled CPU usage, leading to a Denial of Service in the DNSSEC-validating resolver side. 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.
