Descriptions
An issue was discovered in adns before 1.5.2. adnshost mishandles a missing final newline on a stdin read. It is wrong to increment used as well as setting r, since used is incremented according to r, later. Rather one should be doing what read() would have done. Without this fix, adnshost may read and process one byte beyond the buffer, perhaps crashing or perhaps somehow leaking the value of that byte.
Se detectó un problema en adns versiones anteriores a 1.5.2. adnshost maneja inapropiadamente una falta de una nueva línea final en una lectura estándar. Es incorrecto incrementar el uso así como establecer r, ya que el uso se incrementa de acuerdo con r, más adelante. Más bien uno debería estar haciendo lo que la función read() habría hecho. Sin esta corrección, adnshost puede leer y procesar un byte más allá del búfer, quizás bloqueándose o de alguna manera perdiendo el valor de ese byte
