Descriptions

An issue was discovered in adns before 1.5.2. It fails to ignore apparent answers before the first RR that was found the first time. when this is fixed, the second answer scan finds the same RRs at the first. Otherwise, adns can be confused by interleaving answers for the CNAME target, with the CNAME itself. In that case the answer data structure (on the heap) can be overrun. With this fixed, it prefers to look only at the answer RRs which come after the CNAME, which is at least arguably correct.

Se detectó un problema en adns versiones anteriores a 1.5.2. No ignora las respuestas aparentes antes del primer RR que se encontró la primera vez. cuando esto es corregido, el segundo escaneo de respuestas encuentra los mismos RR en el primero. De lo contrario, adns pueden ser confundida entrelazando respuestas para el objetivo CNAME, con el propio CNAME. En ese caso, la estructura de datos de la respuesta (en la pila) puede ser desbordada. Con esto corregido, prefiere mirar solo los RR de respuesta que vienen después del CNAME, que al menos es posiblemente correcto
