CVE-2018-6405

Estado: ModificadaMedia (6.5)—

En la función ReadDCMImage en coders/dcm.c en ImageMagick, en versiones anteriores a la 7.0.7-23, cada variable redmap, greenmap y bluemap puede ser sobrescrita por un nuevo puntero. El puntero anterior se pierde, lo que conduce a una fuga de memoria. Esto permite que atacantes remotos provoquen una denegación de servicio.
