Name of the Vulnerable Software and Affected Versions: PowerDNS Recursor versions 4.0.0 through 4.0.6

Description: A memory leak issue has been found in the DNSSEC parsing code when parsing specially crafted DNSSEC ECDSA keys. This issue occurs when validation is enabled by setting dnssec to a value other than 'off' or 'process-no-validate' (default).

Recommendations: For PowerDNS Recursor versions 4.0.0 through 4.0.6, consider disabling DNSSEC validation by setting dnssec to 'off' or 'process-no-validate' as a temporary workaround to minimize the risk of exploitation.
