CVE-2017-15094

An issue has been found in the DNSSEC parsing code of PowerDNS Recursor from 4.0.0 up to and including 4.0.6 leading to a memory leak when parsing specially crafted DNSSEC ECDSA keys. These keys are only parsed when validation is enabled by setting dnssec to a value other than off or process-no-validate (default).

Se ha encontrado un problema en el código de análisis DNSSEC de PowerDNS Recursor, desde la versión 4.0.0 hasta la 4.0.6, también incluida, lo que conduce a una fuga de memoria al analizar claves DNSSEC ECDSA especialmente manipuladas. Estas claves solo se analizan cuando la validación está habilitada mediante la configuración de dnssec a un valor distinto de off o process-no-validate (por defecto).
